Hypersonic flows

We employ both numerical and experimental approaches to study aerodynamics and heat transfer phenomena encountered by hypersonic re-entry space vehicles with complex 3D geometry.

Advanced experimental techniques are used to investigate the flow physics and develop methods for reducing the adverse effects of shockwave-boundary layer interaction and improving the controllability of hypersonic vehicles. The group has extensive experience in numerical simulations of chemically and thermodynamically non-equilibrium hypersonic flows, heat and mass transfer in free-molecular, transitional and continuum regimes of flows which also incorporate turbulence, chemical reactions and radiation.

Our research is carried out in close collaboration with TsAGI (Central Aerohydrodynamic Institute) and Moscow Institute of Physics & Technology.

Research focus

  • Application of structured and unstructured grids (prisms, pyramids, hexahedrons, tetrahedrons) for complex 3D configurations
  • Numerical modeling of laminar-turbulent transition in hypersonic flows
  • Numerical modeling of equilibrium & non-equilibrium chemical processes and rarefied gases
  • Development of high-performance algorithms based on domain decomposition
  • Development of advanced flow visualization and measurement techniques for hypersonic flow applications
  • Investigation of flow physics of shockwave-boundary layer interactions and associated heat transfer phenomena
  • Control of shockwave-boundary layer interactions using both passive and active flow control technologies

Applications

Facilities

We have a blow-down hypersonic wind tunnel which is capable of delivering a steady hypersonic flow at M=4, 5 and 6 with a run time of about 7 seconds. The wind tunnel is equipped with:

  • A model mounting string which allows the measurement of aerodynamic forces on a model at a range of incidence angles
  • High-speed Schlieren visualisation system
  • Full-surface temperature and pressure measurement systems (temperature- and pressure-sensitive paints)
  • 2D PIV system.

In-house CFD codes have been developed to enable:

  • High accuracy approximation of governing equations for complex geometries
  • Use of different formats for computational grids (Pointwise, ICEM, lab's generator)
  • Adaptation to different architecture of high performance computers
  • Combined use of very different numerical solvers
