Numerical modeling of interaction of a supersonic gas flow with the nozzle case

The numerical methods, algorithms and schemes used for solution of a problem of interaction of the shock wave formed at launch of a rocket engine and the elastic deformable nozzle are considered. The article given a discussion of the revealed delay of a shock wave, in relation to the analytically calculated. The numerical results received with use of various numerical schemes are compared. The analysis of the various factors affecting the pattern of the flow and deformation of the case of a nozzle is carried out.
