This book was released on 2013 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This numerical study is directed at exploring the flow characteristics and thermal response for the flow over a circular cylinder(s) embedded in a horizontal packed bed under steady or unsteady forced convection. The analysis is made for an incompressible fluid flow through a two-dimensional bed, which consists of spherical particles that are packed randomly. The subproblems that are considered in the present study are: First, forced convective steady and pulsatile cross flows over a single cylinder placed in a porous bed. Where, for steady flow, the effects of the thermal and structural properties of the porous medium on the convective and conductive heat transfer to the fluid and solid phases, are examined. While, for pulsatile flow, the flow and heat transfer is investigated subject to a sinusoidally varying inlet flow, for both a non-filled and porous material filled channels. The effects of pulsation frequency and amplitude on heat transfer are quantified. Second, forced convective steady cross flow over multiple cylinders arranged in two staggered or in-line configurations, embedded in a porous bed.The focus is directed on how the spacing parameter between the cylinders affects heat transfer from each, at different thermal conductivity ratios and Reynolds numbers for both configurations.Specifically, the generalised momentum model, i.e., the Darcy-Brinkmann-Forchheimer (DBF) model, is employed to model the flow field. This takes into consideration the non-Darcian terms, such as inertial and viscous effects. Moreover, the energy transport within the solid and fluid phases is modelled using separate energy equations for each phase. This is sometimes called the Local Thermal Non-Equilibrium (LTNE) model, in that it makes no assumptions about local thermal equilibrium between phases. The additional convective heat transfer term between the fluid and solid phases, which emerges when using the two-phase model, is formulated using a documented empirical correlation. Furthermore, the thermal dispersion phenomenon due to the complex path of local fluid elements through the solid matrix, causing mixing and recirculation in both the longitudinal and the transverse directions, is incorporated in the modelling of the fluid phase energy equation.

Download or read book A Numerical Investigation of the Effects of Flow Pulsations Over a Cylinder on Dynamic Forces and Heat Transfer written by Eric J. D'herde and published by . This book was released on 2011 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow over a fixed circular cylinder is a fundamental fluid mechanics problem that involves a simple geometry; yet, as the Reynolds number is incremented, increasingly complex flow patterns emerge. Most notably, when the Reynolds number exceeds a value of about 46, a Bénard-von Kaŕmán vortex street pattern appears. It is associated with a characteristic natural vortex shedding frequency. The objectives of this study are to numerically investigate the effects of an incoming free-stream velocity pulsation with a mean Reynolds number of 100 on the dynamic forces acting on a fixed circular cylinder, on the flow regimes behind the cylinder, and on heat transfer between the cylinder and surrounding fluid. Sinusoidal free-stream pulsations with velocity amplitude A (subscript velocity symbol) values of 25%, 50% and 75% that of the mean free-stream velocity and selected frequencies in the range of one fourth the natural shedding frequency f (subscript s) were considered. Of particular interest, is the interaction between forced pulsating frequencies and the natural vortex shedding frequency. At frequencies close to the natural frequency, and to twice the natural frequency, sudden reductions in the mean value of the drag coefficient are observed, as the imposed frequency increases. These sudden reductions are accompanied by complex changes in flow regimes and vortex shedding patterns. The complexity of flow regimes as a function of the imposed pulsation variables was compiled into a frequency-amplitude map. This original map enables one to correlate changes in flow regimes to both dynamic forces and heat transfer characteristics. No net mean drag reduction was observed in the range of dimensionless amplitudes and frequencies considered, at a Reynolds number of 100. Local heat transfer enhancements up to 86% were achieved for a specific frequency-amplitude pair. A particular finding is the appearance, for a narrow range of frequencies, of a non-zero mean lift coefficient, despite the overall symmetry of the problem. This phenomenon, which was observed in experiments, is reminiscent of the bifurcation responsible for the emergence of the Bénard-von Kaŕmán vortext street.

Download or read book Computation of Viscous Incompressible Flows written by Dochan Kwak and published by Springer Science & Business Media. This book was released on 2010-12-14 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is intended as a concise and self-contained guide to practitioners and graduate students for applying approaches in computational fluid dynamics (CFD) to real-world problems that require a quantification of viscous incompressible flows. In various projects related to NASA missions, the authors have gained CFD expertise over many years by developing and utilizing tools especially related to viscous incompressible flows. They are looking at CFD from an engineering perspective, which is especially useful when working on real-world applications. From that point of view, CFD requires two major elements, namely methods/algorithm and engineering/physical modeling. As for the methods, CFD research has been performed with great successes. In terms of modeling/simulation, mission applications require a deeper understanding of CFD and flow physics, which has only been debated in technical conferences and to a limited scope. This monograph fills the gap by offering in-depth examples for students and engineers to get useful information on CFD for their activities. The procedural details are given with respect to particular tasks from the authors’ field of research, for example simulations of liquid propellant rocket engine subsystems, turbo-pumps and the blood circulations in the human brain as well as the design of artificial heart devices. However, those examples serve as illustrations of computational and physical challenges relevant to many other fields. Unlike other books on incompressible flow simulations, no abstract mathematics are used in this book. Assuming some basic CFD knowledge, readers can easily transfer the insights gained from specific CFD applications in engineering to their area of interest.
