The demand of a more comprehensive engineering tool for parametric investigations of rocket thrust chambers thermal environment is pushing the improvement of hot-gas side heat transfer prediction tools. In this work, the capability of predicting the heat transfer characteristics of a literature test case for a liquid oxygen / gaseous methane single element combustion chamber is assessed by means of 2D axis-symmetric Reynolds-Averaged Navier-Stokes simulations. A simplied approach is proposed, where combustion is not simulated, but combustion products enter the chamber through a pseudo-injector. The numerical results show a good agreement with the experimental data, except in the near injection region.

Abstract

The demand of a more comprehensive engineering tool for parametric investigations of rocket thrust chambers thermal environment is pushing the improvement of hot-gas side heat transfer prediction tools. In this work, the capability of predicting the heat transfer characteristics of a literature test case for a liquid oxygen / gaseous methane single element combustion chamber is assessed by means of 2D axis-symmetric Reynolds-Averaged Navier-Stokes simulations. A simplied approach is proposed, where combustion is not simulated, but combustion products enter the chamber through a pseudo-injector. The numerical results show a good agreement with the experimental data, except in the near injection region.
