General information

Name of the project: Quantitative and experimental research of non-equilibrium flows with applications to spacecraft

Strategy for Scientific and Technological Development Priority Level: е

Goals and objectives

Research directions:

Finding fundamental physical laws and solving applied aerospace problems in aerodynamics of prospective spacecraft, traditional and state-of-the-art technologies of creating reactive drag, gas and multiphase flows in microdevices and micromuzzle, developing of instability and laminar-turbulent transition in hypersound flows

Project objective: Obtaining new fundamental knowledge that will allow us to significantly enhance understanding of non-equilibrium flows drastically improving capabilities of researchers and engineers in describing and forecasting their qualities as well as to lay the scientific basis for developing new generations of spacecraft

The practical value of the study

  • New powerful supercomputer software for quantitative modeling of non-equilibrium flows has been created.
  • We have developed new methods and tools for experimental research of non-equilibrium flows, in particular, a method to determine composition and structure of disturbances in hypersound flows based on mode decomposition.
  • Our researchers have conducted computations of high altitude aerodynamics of spacecraft in transitional flow modes using hybrid supercomputers accounting for ionization, radiation and surface recombination, modeling control of transition to turbulence in the transitional layer at big Mach number values.

Implemented results of research:

  • We have received several patents for methods to modernize hypersound high enthalpy aerodynamic tubes that have been used to conduct works within contracts for the defense industry. We have conducted research of heating surface of aircraft and provided characteristics of distributed and integral heat flows on its surface.
  • Computational and experimental research methods for non-equilibrium processes in hypersound flows developed at the Laboratory is used in several project of the Russian Foundation for Basic Research, the Russian science foundation and in state budget-sponsored works of the Khristianovich Institute of Theoretical and Applied Mechanics of the Siberian Department of the Russian Academy of Sciences.

Education and career development:

  • Internships for 10 undergraduates, postgraduates and young scientists.
  • We have organized the «Workshop on Non-equilibrium Flow Phenomena in Honor of Mikhail Ivanov's 70th Birthday» (2015).
  • 2 doctoral dissertation, 5 candidate dissertation have been defended.
