Abstract
The purpose of this work is the modeling and simulation of hydrogen-oxygen components mixing and chemically reacting in liquid rocket combustion chambers using OpenFOAM. It is a free, open source CFD software capable of simulating complex fluid flows involving heat transfer, chemical reactions and turbulence. The numerical assessment was performed using reactingFoam, a solver based in the Favre-Navier-Stokes equations. As part of the numerical results can be mentioned the pressure oscillations acoustic waves and the speed oscillation patterns in the rocket combustion chamber.
