N2 - The use of a high-temperature jet vortex valve without moving parts for the secondary jet of the vector nozzle can meet the needs of the secondary jet flow regulation of the vector nozzle in a high temperature and high pressure environment. The high-temperature jet vortex valve is a valve device with a certain amplification effect that uses a small cold flow to regulate a large flow of high-temperature gas flow. This paper uses numerical simulation to investigate the flow field distribution and flow adjustment characteristics of the vortex valve in different control pressure ratio when the main gas pressure of the vortex valve is 16 MPa and the temperature is 2500K. The results show that the high-temperature jet vortex valve relies on different radial pressure gradients generated by different control flow pressures could achieve the effect of adjusting the flow rate of high-temperature and high-pressure gas. The results proved the feasibility of the vortex valve in adjusting the secondary jet flow rate of the nozzle; further exploring indicated that the flow adjustment ratio TD will change when the ratio of the control flow port area to the outlet area changes.
