Flow Analysis of Butterfly Valve Using CFD
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 6
Abstract
Butterfly valves are widely used in hydro power plants to regulate and control the flow through hydraulic turbines. That’s why it is important to design the valve in such a way that it can give best performance so that optimum efficiency can be achieved in hydraulic power plants. Conventionally that the models of large size valves are straight in the laboratory to determine their performance characteristics. This is a time consuming and costly process. High computing facility along with the use of numerical techniques can give the solution to any fluid flow problem in a lesser time. In this research work flow analysis through butterfly valve with aspect ratio 1/3 has been performed using computational software. For modelling the valve ICEM CFD 12 has been used. Valve characteristics such as flow coefficient and head loss coefficient has been determined using CFX 12 for different valve opening angle as 30°,60°,75°, and 90° (taking 90°as full opening of the valve) for incompressible fluid. Value of head loss coefficient obtained from numerical analysis has been compared with the experimental results.
