Abstract
Computational fluid dynamics (CFD) enables scientists and engineers to perform ‘numerical experiments’ (i.e., computer simulations) in a ‘virtual flow laboratory’. Numerical simulation permits valve manufacture to determine valve sizing coefficients and to solve problems involving valves fluid flow. Valve designer via CFD could identify and eliminate valve flow problems before starting the manufacturing step. This technique is less costly alternative to determine the flow coefficients based on CFD calculations. Butterfly valves are versatile components widely used in hydraulic systems as shutoff and throttling valves. In this study, a comprehensive 3D simulation study for 2" (50 DN STC model) butterfly valve is conducted to establish a trusted and a calibrated numerical solution model after comparing with experimental data. The goal of this study is to verify and validate CFD code to obtain reasonable results for control valve coefficients calculation. The steady and incompressible Navier-Stokes equations are solved numerically to predict the flow behavior and compute the pressure loss, flow, and torque coefficients.
