Abstract
Hydrogen–oxygen fuels are very attractive now for rocket engines designers, because this pair is ecology friendly. Computer aided design of new effective and clean hydrogen engines needs mathematical tools for supercomputer modeling of hydrogen–oxygen components mixing and combustion in rocket engines. The paper presents the results of developing, verification and validation of mathematical model making it possible to simulate unsteady processes of ignition and combustion in rocket engines. • Predictive modeling 3-D code was developed to simulate chemically reacting turbulent flows. • The code was tested on simulating model combustion chamber fed by hydrogen and oxygen. • Unstable regimes in rocket engines and their stabilization were studied. • Chocking regimes in rocket engines were detected under definite initial conditions.
