Effects of non-equilibrium chemical reaction flow on the performance of scramjet nozzle
The RNG k-ε turbulence models and finite volume method were used to solve the conservative Reynolds-averaged Navier-Stokes equations.7-specice
8-step finite-rate chemical reaction models were employed to calculate the flow of the scramjet single expansion ramp nozzle.The characteristics of the nozzle were numerically studied under various free-stream Mach numbers and various flight heights.The calculation shows that the performances of the nozzle are notably advanced under the combustion in the nozzle.The non-equilibrium chemical reactions should always be considered in research of the performance of scramjet nozzle.
