The aim of the work is the creation of computational and experimental methodical aids for determinig the parameters of continuows medium flows in complex-profile mains in application to particular engineering systems, in hydraulically connected compartments of rocket-and-space systems. Methods of research are theoretical, based on numerical solution of nonstationary - gas - dynamics ecuations, and experimental methods. In the report, the description of the mathematical model for the nonstationary quasi-one-dimensional vap our-air mixture flow computation in a channel, as well as numerical calculations results for nonstationary flow parameters in a channel with regard for heat abstractionare presented. The results of numerical investigations are presented for different parameters influence on gas issue at sub-and supersonic regimes; computational and experimental research results for a kerosene vapour conversion process are given; a des-cription is presented for a test rig put into operation to experimentally investigste gasdynamic characteristics of the thermostatting systems of LV and SV compartments, and the results of exploratory-methodical development in the course of research an as a part of the test rig of the exhaust system model. The research results are possible to be used in power engineering and machine-building. Product Description popup.authors popup.nrat_date 2020-04-03 Close
