Computational Fluid Dynamics Based Analysis of Automatic Shutoff Valve
The use of kinetic energy of fluids has been intelligently employed over the years for performing various functions in different engineering processes. One of the common applications is the functioning of aeroplanes. Furthermore, the use of this energy has been extended to applications in devices like turbomachinery, valves, etc. Valves are of utmost importance for the safe operation of industries as these manage the flow of fluids. Energy plays a vital role in every aspect and thereby valves are also developed to attain optimum working capability. The principle of kinetic energy of fluids forms the basis of Automatic Shutoff Valve (ASV). The energy associated with the moving fluid helps in performing the functioning of the valve. This paper investigates the performance of ASV using CFD. The performance analysis is based on the flow coefficient of the valve, pressure drop across the valve and torque generated on the closing member.
