Abstract

The characteristics of film cooling in a CH4/O2 sub-scale chamber with multi-injector elements and two kinds of film cooling slot dimensions are investigated using a calorimeter chamber in experiments and simulations, in which the finite rate chemistry with a reduced CH4/O2 reaction mechanism is taken into account. The computed wall heat flux and pressure distributions are compared to the experimental results, which overall show good agreement. A large slot dimension is shown to induce mixing with a core flow. This mixing causes a low heat flux distribution near a face plate along with high combustion efficiency.
