Unsteady thermo-gasdynamic processes in rectangular scramjet combustion chamber with periodical input of cold air

Combustion of hydrogen-air mixture under a periodical perpendicular injection of cold air is modeled. Fields of chemical species concentrations, pressure, and temperature are calculated by two-dimensional computational model based on unsteady governing equations including Navier-Stokes equations, energy conservation and diffusion equations together with system of chemical kinetic equations. Two-dimensional temperature, pressure and velocity visualization are presented. Method of the numerical simulation and details of the problem under consideration are presented in Ref.4.

Нестационарные газодинамические процессы в прямоугольном канале ГПВРД с периодическим вдувом холодного воздуха

В работе моделируется процесс горения водородо-воздушной смеси при периодическом вдуве холодного воздуха поперек основного сверхзвукового потока. Поля концентраций химических компонент, давления и температуры рассчитываются с помощью двумерной вычислительной модели, основанной на нестационарных уравнениях Навье-Стокса, сохранения энергии, уравнений диффузии и системы уравнений химической кинетики. Представлена визуализация двумерных расчетов полей температуры, скорости, давления и концентраций химических компонент.
