Abstract

SERN (Single Expansion Ramp Nozzle) nozzles often used in many aerospace vehicles with Scramjet engines. Employment of SERN nozzles results in reducing the frictional drag and weight of nozzle and also they produce extra lift. A numerical study of supersonic gas flow in SERN nozzles is presented in this paper. The Navier-Stokes equations are solved with using a FORTRAN code. The governing equations are conservation of mass, momentums, energy and state equation of perfect gas for two dimensional compressible viscose flow. Equations are solved with using time-marching method. For verification, the results of recent Numerical solution are compared with experimental results and results of Fluent and results of method of characteristics (MOC) and comparisons show good agreement with experimental results and other Numerical solutions.
