Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to investigate experimentally the rectangular jet flow that impinges to a flat plate normally and obliquely. The aspect ratio (nozzle exit height / nozzle exit width) of the rectangular nozzle is 2.First, to investigate the characteristics of the coming flow to the impingement surface, the free jet conditions are examined by using three different Reynolds numbers based on the nozzle exit width as 3.47x 10 4, 6.94x 10 4 and 1.04x 10 5. Then, the effect of the ratio of the nozzle-to-plate distance to nozzle exit width, H/w, on the jet impingement flow is studied for the Reynolds number of 1.05x10 5. H/w ratio is taken as 2.0, 3.08, 4.0, 6.0 and 8.0. To examine the effect of the 8, which is the angle between the jet centerline axis and the surface normal axis, on the jet impingement characteristics, q is taken as 0 o, 5 o, l0o, 15 o and 20 o.The mean velocity and turbulence intensity profiles are measured by using hot-wire anemometer. The outputs of the hot-wire system are taken and drown by a personal computer with a hot-wire software and data acquisition card. Impingement surface pressures, according to the pressure at settling chamber are measured by using a micro manometer which is connected to a personal computer with a data acquisition card. In this study, the surface oil-film technique is used to visualize the impingement surface flow pattern and smoke method is used to visualize the flow pattern of the free jet and jet impingement to a flat surface.This study consists of five main sections (Chapter 1-5) and 6 appendix (Appendix A-F).Chapter 1 is introduction. The importance of the subject, the purpose of the study and the experimental techniques that were used are mentioned..In Chapter 2., information about free jet flow and jet impingement according to literature review is given.Chapter 3., explains the instrumentation and experimental techniques.In Chapter 4. results and discussion are given. Concluding remarks are made in Chapter 5.

Download or read book The Impingement of a Circular Jet Normal to a Flat Surface with and Without Cross Flow written by Paul E. Colin and published by . This book was released on 1969 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow field resulting from a circular jet impinging on a flat surface in a main cross-flowing stream was investigated. A cross-flowing stream produces considerable changes to the flow field of a jet impinging on a flat surface. Separation of the radial wall jet occurs along a horse-shoe shaped line with the formation of a separation bubble whose dimensions can be large compared to the jet nozzle diameter for large values of the jet to free stream velocity ratio. Because of the very high levels of turbulence encountered in the separation bubble, measurements with pressure or electrical probes were restricted to limited regions of the flow field. As a result, extensive use was made of flow visualization techniques. The results presented bring out some of the typical characteristics of the flow field investigated. An analysis is proposed to explain and predict some of these characteristics. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An incompressible, inviscid rotational flow model is used to represent the normal impingement of axisymmetric jets and the oblique impingement of two-dimensional jets upon a flat surface. The Poisson-type equation that results from this formulation is cast into suitable finite difference form and solved by relaxation techniques. Results, in terms of the ground plane pressure distribution, centerline velocity decay, and oblique impingement flow field structure, compare well with observations. (Author).

Download or read book Comparison of Heat Transfer and Fluid Flow Characteristics Between Submerged and Free Surface Jet Impingement for Two-phase Flow written by Victoria J. Rouse and published by . This book was released on 2018 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impinging jets have been studied in great depth due to their high rates of heat transfer and wide range of application. Some applications of impinging jets include electronic equipment cooling, metal annealing, furnace heating, and many others. The goal of this research was to understand the effects of the nozzle-to-plate spacing and volumetric quality on the Nusselt number of two-phase, free surface impinging jets and submerged impinging jets. The Nusselt number of two-phase, free surface and submerged impinging jets were obtained at several nozzle-to-plate spacings and the trends of the stagnation pressure and Nusselt number were compared. The Nusselt number of the submerged jet was also compared to that of the free surface jets with the same conditions. The two working fluids of the jet were water and air. The nozzle-to-plate spacing ranged from H/d = 0.03 - 8.5 and the experiment was done at five volumetric qualities. The Nusselt number and stagnation pressure decreased exponentially in both free surface and submerged jets for all volumetric qualities in Region I, the jet deflection region. In Region II, the transition region, the Nusselt number and stagnation pressure of the free surface jet remained constant with some fluctuation. The Nusselt number and stagnation pressure of the submerged jet continued to decrease linearly. In Region III, the free jet region, the Nusselt number and stagnation pressure increased linearly in the free surface jet and decreased linearly in the submerged jet. Comparing the values of the free surface and submerged jet, the submerged jet had a higher Nusselt number for low nozzle-to-plate spacings, and a lower Nusselt number for higher nozzle-to-plate spacings.

Download or read book Turbulent Jets and Plumes written by Joseph Hun-wei Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jets and plumes are shear flows produced by momentum and buoyancy forces. Examples include smokestack emissions, fires and volcano eruptions, deep sea vents, thermals, sewage discharges, thermal effluents from power stations, and ocean dumping of sludge. Knowledge of turbulent mixing by jets and plumes is important for environmental control, impact and risk assessment. Turbulent Jets and Plumes introduces the fundamental concepts and develops a Lagrangian approach to model these shear flows. This theme persists throughout the text, starting from simple cases and building towards the practically important case of a turbulent buoyant jet in a density-stratified crossflow. Basic ideas are illustrated by ample use of flow visualization using the laser-induced fluorescence technique. The text includes many illustrative worked examples, comparisons of model predictions with laboratory and field data, and classroom tested problems. An interactive PC-based virtual-reality modelling software (VISJET) is also provided. Engineering and science students, researchers and practitioners may use the book both as an introduction to the subject and as a reference in hydraulics and environmental fluid mechanics.

Download or read book Aerodynamics of a Lifting System in Extreme Ground Effect written by Kirill V. Rozhdestvensky and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the memory of a distinguished Russian engineer, Rostislav E. Alexeyev, who was the first in the world to develop the largest ground effect machine - Ekranoplan. One of Alexeyev's design concepts with the aerodynamic configuration of a jlying wing can be seen on the front page. The book presents a description of a mathematical model of flow past a lifting system, performing steady and unsteady motions in close proximity to the underlying solid surface (ground). This case is interesting for practical purposes because both the aerodynamic and the economic efficiency of the system near the ground are most pronounced. Use of the method of matched asymptotic expansions enables closed form solutions for the aerodynamic characteristics of the wings-in-ground effect. These can be used for design, identification, and processing of experimental data in the course of developing ground effect vehicles. The term extreme ground effect, widely used through out the book, is associated with very small relative ground clearances of the order of 10% or less. The theory of a lifting surface, moving in immediate proximity to the ground, represents one of the few limiting cases that can be treated analytically. The author would like to acknowledge that this work has been influenced by the ideas of Professor Sheila E. Widnall, who was the first to apply the matched asymptotics techniques to treat lifting flows with the ground effect. Saint Petersburg, Russia February 2000 Kirill V. Rozhdestvensky Contents 1.

Available in PDF, EPUB and Kindle. Book excerpt: Since the education of aeronautical engineers at Delft University of Technology started in 1940 under tae inspiring leadership of Professor H.J. van der Maas, much emphasis has been placed on the design of aircraft as part of the student's curriculum. Not only is aircraft design an optional subject for thesis work, but every aeronautical student has to carry out a preliminary airplane design in the course of his study. The main purpose of this preliminary design work is to enable the student to synthesize the knowledge ob tained separately in courses on aerodynamics, aircraft performances, stability and con trol, aircraft structures, etc. The student's exercises in preliminary design have been directed through the years by a number of staff members of the Department of Aerospace Engineering in Delft. The author of this book, Mr. E. Torenbeek, has made a large contribution to this part of the study programme for many years. Not only has he acquired vast experience in teaching airplane design at university level, but he has also been deeply involved in design-oriented re search, e.g. developing rational design methods and systematizing design information. I am very pleased that this wealth of experience, methods and data is now presented in this book.

Book excerpt: Hypersonic Flow Theory presents the fundamentals of fluid mechanics, focusing on the hypersonic flow theory and approaches in theoretical aerodynamics. This book discusses the assumptions underlying hypersonic flow theory, unified supersonic-hypersonic similitude, two-dimensional and axisymmetric bodies, and circular cylinder. The constant-streamtube-area approximation, streamtube-continuity methods, and tangent-wedge and tangent-cone are also deliberated. This text likewise covers the similar laminar boundary layer solutions, bluntness induced interactions on slender bodies, and free molecule transfer theory. The dynamics of hypersonic flight or hypersonic wing theory, magnetohydrodynamic theory, or any developments involving treatment of the Boltzmann equation are not included. This publication is intended for hypersonic aerodynamicists, students, and researchers conducting work on the hypersonic flow phenomena.
