| Abstract: | A control valve is designed to regulate the mass flow in a short duration turbine test facility. The flow patterns in the throat of valve is calculated and optimized with a CFD code. By means of modifying the throat profiles, the controlling ability of the valve has been enhanced significantly compared with the prototype design. By using of the CFD code, the flow field through the valve tail part, corresponding to three design tail profiles are analyzed and compared. Considering a number of factors affect the performance and manufacture cost, a compromised tail profile design has been selected. |
