Numerical Simulation of Jet Pipe Servo Valve
Tehnicki vjesnik - Technical Gazette, 2020 The jet pipe servo valve (jet valve) is the most widely used flow control servo valve on aircrafts and spacecrafts. However, the valve has not been simulated accurately due to its special structure and complex internal flow field. The structure design and performance analysis of the valve mainly rely on repeated experiments, which greatly limits the ...
