Numeral research of jet, expanding in a limited space with complex configuration

摘要

In this article a mixed convection of homogenous gas in a rectangular closed area is investigated. A gas stream is blown through a slot in the center on the lateral surface. To describe the considered stream, an equation system is derived from the Nawie-Stocks model for compressable gas at opproaching hypersonic motion. For internal body a head convectivity equation is used. Satterland formula is used on dynamic viseous coefficient. The problem presented above is solved numerically with a method enabling to apply implicit schemes of alternative directions for the solution of the system of the equations. The main reults of the calculations are given grafically and relevant conclusions are made.
