Abstract
A design method of alterable section serpentine stealth nozzle based on coupled parameters was presented in this paper. The high temperature turbine was shielded completely by the nozzle designed. Numerical simulations of the double serpentine nozzle designed were carried out using CFD software. The computational results showed that the Ma distributions along the cross sections of double serpentine nozzle were non-homogenous. Local high velocity zones existed at the leeward down the first turning and the second turning of the nozzle. Even though air deflected twice by reason of nozzle turnings, there were no separation bubbles inside the nozzle. Two main total pressure loss regions existed at the two turnings of the double serpentine nozzle.
