As the key component of gas turbine for fuel flow control
gas fuel control valve directly affects the stability and safety of gas turbine operation. Low-pressure air was used to replace gas
and the gas fuel control valve was modeled and tested. The accuracy of the simulation calculation was verified by comparing the results. The numerical simulation and flow loss analysis were conducted on the prototype valve. Results show that based on premise of geometric similarity
the same pressure ratio and Mach numbers
and the Reynolds number in the self-modeling area
the modeling experiment can well reflect the flow and loss characteristics of the prototype valve. The root mean square error of mass flow between the simulated value and the experimental value is 3.26%. As the opening degree of valve increases
the shock wave generated by the valve expansion section can reduce the pressure loss before and after the valve. As the pressure ratio of the gas fuel control valve decreases
the high-speed area of the valve throat gradually expands and the flow rate slowly decreases.
