“…The equation system is closed by the differential model of turbulence and by the kinetic scheme of gaseous fuel combustion in air. In this paper we describe the calculations performed using a turbulence model q-ω with a blending function (as in SST model), with taking into account the compressibility effects and with turbulence production correction [7]. In these calculations, a simplified model of chemical kinetics will be used, including the quasi-global reaction of hydrocarbon fuel oxidation to CO and H 2 O and 11 reactions between H, O, OH, H 2 O, O 2 , H 2 , CO, CO 2 with inert gas N 2 [8] as well as model of the propane burning in the air [9].…”

Fast technologies for numerical simulation of high-speed flows in ducts, developed in TsAGI, are described. The examples are presented of the application of experimental data, obtained at T-131 wind tunnel, for validation of the developed numerical technologies: 1) validation of 2.5D and 3D calculations of flow in the elliptic combustor with hydrogen supersonic combustion that was studied within HEXAFLY-INT international project; 2) validation of 2D and 2.5D calculations of flow in high-speed model combustor duct with step-like expansion. Preparation of new series of experiments, oriented on validation of turbulent combustion models, is described.

“…An important original peculiarity of the "wall law" boundary condition is the using self-similar profiles of source terms for the turbulence parameters in the balance equations for the near-wall cell. Details of this boundary condition are given in [7].…”

Model high-speed combustor on gaseous hydrocarbon fuel, prepared for experiments in T-131 wind tunnel of TsAGI, is presented. Experiments are projected to create an experimental database for validation of calculations and physical models of turbulence and combustion. Geometry of combustor and prepared measurements are described. The main subject of paper is preliminary calculations of this combustor. Numerical methods for 2D and 3D URANS calculations are described. Special attention is given to numerical techniques allowing fast calculations of 3D unsteady flow development in the combustor. Approach to parallel realization of Fractional Time Stepping (FTS) technology is described. One way of In Situ Adaptive Tabulation (ISAT) of kinetic equations solution during the calculation is presented. Possible gasdynamic structure of flow in the combustor with the flame stabilization both in subsonic and in supersonic regime is described. Asymmetrical stationary solution (for the symmetrically-expanding duct) and symmetrical solution with flame oscillations are found and analyzed.
