Available in PDF, EPUB and Kindle. Book excerpt: Valves are critical components in a fluid flow network. Based on the type of fluid used, valves may suffer unforeseen wear and tear that might lead to an inadvertent failure. Major work in this thesis is focused on high pressure water valves that are used for descaling purposes. Controlling fluid flow at high pressures is not only challenging but also becomes time-wise critical. Failure of one such high pressure un-loader valves was studied first for the feasibility of my thesis work. A reverse flow operation was set in one such valve due to piping constraints established by industrial requirements. Experience and data recording showed that the premature failures of such valves by BOC Water Hydraulics were seen in months which lasted for years in standard operation. Computer simulation was being utilized to understand the fluid phenomena at such high pressures. The highly energized fluid from the descaling pump sets off a static pressure of 4300 psi at the valve inlet. It is responsible for continuous fluid flow rate of up to 208 gpm when the valve becomes fully open. Computational Fluid Dynamics (CFD) approaches are widely being utilized for fluid research in design optimizations. A Standard Turbulence model was used to understand the fluid flow variables using velocity/pressure contours for several possible valve opening positions. A very low pressure developed below the poppet seat of the valve suggests the onset of cavitation zones which may lead to leakage. Leakage at such a descaling pressure further accounts for cavitation and may which ultimately affect valve's overall performance resulting in cartridge replacement. Using CFD, the poppet valve assembly was modeled and simulated using ANSYS Fluent, commercially available CFD software. Low pressure below the atmospheric gage pressure in the valve body is found to be responsible for the initial onset of cavitation.

Book Synopsis Perspectives in Flow Control and Optimization by : Max D. Gunzburger
Download or read book Perspectives in Flow Control and Optimization written by Max D. Gunzburger and published by SIAM. This book was released on 2003-01-01 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow control and optimization has been an important part of experimental flow science throughout the last century. As research in computational fluid dynamics (CFD) matured, CFD codes were routinely used for the simulation of fluid flows. Subsequently, mathematicians and engineers began examining the use of CFD algorithms and codes for optimization and control problems for fluid flows. Perspectives in Flow Control and Optimization presents flow control and optimization as a subdiscipline of computational mathematics and computational engineering. It introduces the development and analysis of several approaches for solving flow control and optimization problems through the use of modern CFD and optimization methods. The author discusses many of the issues that arise in the practical implementation of algorithms for flow control and optimization, and provides the reader with a clear idea of what types of flow control and optimization problems can be solved, how to develop effective algorithms for solving such problems, and potential problems in implementing the algorithms. Audience: this book is written for both those new to the field of control and optimization as well as experienced practitioners, including engineers, applied mathematicians, and scientists interested in computational methods for flow control and optimization. Readers with a solid background in calculus and only slight familiarity with partial differential equations should find the book easy to understand. Knowledge of fluid mechanics, computational fluid dynamics, calculus of variations, control theory or optimization is beneficial, but is not essential, to comprehend the bulk of the presentation. Only Chapter 6 requires a substantially higher level of mathematical knowledge, most notably in the areas of functional analysis, numerical analysis, and partial differential equations.

Book Synopsis Computational Fluid Dynamics Modeling and Lab Testing of Hydraulic Spool Valves by : Kyle Janosky
Download or read book Computational Fluid Dynamics Modeling and Lab Testing of Hydraulic Spool Valves written by Kyle Janosky and published by . This book was released on 2020 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the goal is to simulate a hydraulic spool valve and be able to predict the flow rate of a valve. Also, to evaluate the impact of pressure difference on the flow without requiring lab testing. This will be done by utilizing traditional lab testing to set up and validate the simulation. This simulation will be done by using Ansys Fluent. A comparison of actual lab data to that of simulation using multiple standard turbulence models will be made in this thesis. Along with turbulence models, there will be comparison as how different solver options impact the results. After choosing the best turbulence model and solver, the simulation will be used to investigate the flow pattern in the valve and the effect of the pressure difference on the flow rate. This will help better correlate future simulations to lab testing, thus reducing the required tests needed to develop new products.

Book Synopsis Computational Fluid Dynamics Analysis of Butterfly Valve Performance Factors by : Adam Del Toro
Download or read book Computational Fluid Dynamics Analysis of Butterfly Valve Performance Factors written by Adam Del Toro and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Butterfly valves are commonly used in industrial applications to control the internal flow of both compressible and incompressible fluids. A butterfly valve typically consists of a metal disc formed around a central shaft, which acts as its axis of rotation. As the valve's opening angle is increased from 0 degrees (fully closed) to 90 degrees (fully open), fluid is able to more readily flow past the valve. Characterizing a valve's performance factors, such as pressure drop, hydrodynamic torque, flow coefficient, loss coefficient, and torque coefficient, is necessary for fluid system designers to account for system requirements to properly operate the valve and prevent permanent damage from occurring. This comparison study of a 48-inch butterfly valve's experimental performance factors using Computational Fluid Dynamics (CFD) in an incompressible fluid at Reynolds numbers ranging approximately between 105 to 106 found that for mid-open positions (30-60 degrees), CFD was able to appropriately predict common performance factors for butterfly valves. For lower valve angle cases (10-20 degrees), CFD simulations failed to predict those same values, while higher valve angles (70-90 degrees) gave mixed results. (152 pages)
