Computer simulation of gas dynamic process for a jet engine

Abstract

In this paper we describe a mathematical model of gas dynamic process in the combustion chamber of a jet engine, programming of this model and visualization of the process. We use the geometric super surfaces 3-D model of the combustion chamber as the boundary conditions for this gas dynamic process. The Program (Visual C++ 6.0) calculates the system of non- linear unsteady equations which describe dynamics of the tough compressible transcalent gas under conditions diffusion and chemical reactions in 3-D space. Visualization of this process gives us color tone 2-D pictures (density, temperature, pressure, direction, and velocity) of gas flow in a chosen section on 3-D stereo translucent image of the jet engine combustion chamber in a current period time. We can use an asynchronous parallel super computer for acceleration of the calculation and visualization of this gas process.
