Методики моделирования процессов горения в камере ракетного двигателя

Abstract

A work presents methods for simulation of burning process in the rocket engine chamber. Has been mentioned four software tools for burning simulation. Here are considered widely used burning models. The detailed calculation of hydrogen-oxygen rocket engine chamber has been performed in ANSYS CFX with Eddy Dissipation model for two sets of chemistry: one global reaction and detailed chemical system with 8 components and 18 reactions. The comparison of results gives more smooth contours of parameters for set with detailed system against variant with one reaction.
