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 Study of Poppet Valves on Flow Fields by : Prashant Mane
Download or read book Computational Study of Poppet Valves on Flow Fields written by Prashant Mane and published by . This book was released on 2013 with total page 182 pages. 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.
