Modelling of the flow structure in a composite jet behind two thrusters located near the spacecraft case

摘要

The gasdynamic flow structure is studied experimentally and numerically in the zone of jet interaction flowing with considerable underexpansion from two supersonic nozzles located near the spacecraft case. Lon-gitudinal and transversal distributions of the density are obtained by the method of electron beam. They are compared with calculation results for inviscid gas. Generalized dependencies for determination of gas density within the zone of two jets interaction and boundary of this zone are obtained.
