The research subjects are heat, gas and plasma dynamic processes in the engineering systems. The research objectives are to create and apply scientific and technical support, methods and facilities for resolving the existing problems in heat, gas and plasma dynamics of the engineering systems. The research methods: nonlinear programming, numerical simulation, physical modelling, laboratory tests, diagnosis of rarefied plasma fluxes, direct numerical simulation (Monte-Carlo methods). The results obtained. Scientific and technical support for the scientific experiments on diagnosis of the ionosphere plasma at a high of about 700 km is developed. Application of sensors with two measuring channels results in a synchronous measurement of a statistic pressure and velocity head of a rarefied gas. Scientific validation of an efficient use of a research diagnostics complex on the Microsat spacecraft is offered. A new version of a source of heavy-current pulse magnetron discharge is developed. Design proposals on an integrated technological device involved the plasma devices for ion-plasma and ion-beam surface treatments are formulated. The test particle Monte-Carlo method is extended using the unstructured computational grids. An algorithm of an iteration construction of two-level hierarchy-block computational grids is proposed. Testing this algorithm over a wide range of the computational parameters indicated significant savings in the computer resources and time-consuming in comparison with TPM computations on the uniform structured grids. Scientific and methodic support for aerodynamic improving a form of compressor vane channels for the aircraft gas-turbine engines is developed using a numerical simulation of 3D turbulent gas flows. For a number of practical important cases an aerodynamic optimization of the compressor rims is performed. Using a numerical simulation, the possibilities of initiating the self-oscillating flows in gas, air and water in delivery of heat, mass and under other environmental conditions are considered. Results of studies of radiative heat exchange and combustion processes in the combustion chambers of solid rocket engines are systematized. Practical recommendations are made to use the results of the study of radiative heat exchange and combustion processes. The research results can be employed for supporting the research and applied aerospace projects and programs. Applications: aerospace industry, power engineering.
