SMILE software system

The SMILE software system is designed for solving non-equilibrium rarefied gas dynamics problems on multiprocessor computers. The system includes a preprocessor module for defining a geometric model of the vehicle and specifying boundary and initial conditions, and a postprocessor module, providing analysis and visualization of the results of simulations.


Hypersonic impulse wind tunnel IT-302M

This unique hypersonic facility allows us to perform experiments at Mach numbers M = 5รท12 and stagnation temperatures up to 3000-4000K, i. e. at conditions close to the real flight. This is indispensable in studies aimed at developing advanced aerospace technologies. Conventional supersonic wind tunnels cannot provide the necessary values of the Reynolds number and the stagnation temperature because of high thermal loads in the wind tunnel channel. In impulse wind tunnels due to the short running time there is an opportunity to invest, by electric discharge, adiabatic compression and combustion reaction, significantly more extra energy in the working gas. For planned experiments the IT-302M wind tunnel will be substantially upgraded. Research will include the schlieren visualization of density gradient field recorded with high-speed camera, measuring the pressure and heat flux fluctuations on the model surface with piezoceramic sensors, atomic-layer thermocouples and high-speed panoramic IR camera.


Supersonic tunnel T-327B

The supersonic wind tunnel T-327B is a small-size aerodynamic facility. At this facility, experimental research on control of the aerodynamic characteristics of reentry vehicles with gas-permeable porous materials will be undertaken. Mesh screens and cellular-porous materials with different spatial structure and porosity will be used as gas-permeable materials. For the first time experiments on the effect of temperature and temperature distribution in a gas-permeable material on the aerodynamic characteristics of the models will be carried out. The necessary temperature fields in gas-permeable materials supposed to be created by a distributed ohmic heating of the gas permeable material. First experiments will also be held to change the temperature of the gas in the pores of cellular-porous materials with an electric discharge. In combination with ohmic heating it allows you to control the flow viscosity in porous materials for the formation of an effective shape of the frontal part of the body in order to create controlled aerodynamic moments.


Low-noise supersonic wind tunnel T-325

The T-325 is a low-noise wind tunnel. It operates at Mach numbers up to 4. The turbulence level in the working section of the wind tunnel is less than a tenth of a percent, which makes it unique for studies of the laminar-turbulent transition at moderate supersonic speeds. The T-325 will be also used for the experiments on boundary layer control.


Gas dynamic facility LEMPUS

A series of experiments will be carried out on the gas-dynamic complex LEMPUS, providing the flow Mach number up to 20. Gas composition at the nozzle exit will be measured by gas chromatography mass spectrometry. This facility will also be used for investigation of processes of hydrocarbon synthesis in plasma chemical reactions. The low-density experimental complex of Department of Applied Physics, Research Sector of Novosibirsk State University include the LEMPUS-1 and LEMPUS-2 gas dynamic facilities and a plasma chemical facility equipped with turbo-molecular and cryogenic pumps, electron guns, modern quadrupole and TOF mass-spectrometers, molecular beam generators, monochromators, liquid nitrogen station, thermostats, computer-aided systems of control and data acquisition. The facility can operate in stationary as well as pulse regimes. The pulse regimes provide a significant extension of the range of gas densities and mass rates and allow us to form non-equilibrium rarefied gas flows.
