Vaulin S.D., Kartasheva M.A. THE METHODS FOR MODELING OF PERFECT GAS IN AN ANNULAR NOZZLESThe methods for modeling of flows of perfect gas in external expansions annular nozzles without an external contour are researched. The flows scheme in external expansions annular nozzle with short-cut center body is considered. The versions of using of finite-difference methods for calculation flows in subsonic, transonic and supersonic fields of flow are proposed. On basis of proposed calculations methods are developed computational algorithms for modeling of gasdynamic and thrust characteristics of external expansions annular nozzle.Key words: external expansions annular nozzle, computational domain, relaxational method, finite-difference scheme.
