Résumé

A marching procedure is used to solve the equation of mass momentum, energy and concentration in the flow. Numerical results for air-water system are presented. The effects of flow conditions on the film cooling mechanism are discussed. Results show that a better liquid film cooling is noticed for a system having a higher inlet liquid temperature, a higher gas flow Reynolds number or a lower liquid flow rate. Additionally, the results indicate that the convection of heat by the flowing water film becomes the main mechanism for heat removal from the interface.
