Heat Transfer in Film-Cooled Bipropellant Thruster 2006-01-2040

A flow in a film cooled bipropellant thruster is simulated for estimating the film-cooling effects. A three dimensional numerical model contains gas phase reactions within a turbulent flow field. The combination of fuel and oxidizer is hydrazine (N2 H4) and NTO (nitrogen tetroxide) respectively. The wall heat flux and its distribution of the chamber wall are numerically obtained, and an average wall temperature is estimated. The estimated temperature and the temperature distribution of the chamber wall show good agreement with the experimental data.
