Keywords: convective, radiative, effusion holes, combustor liners

In order to predict combustor durability, 3D calculations taking into account all physical phenomena (Convection, radiation, conduction) are performed. Indeed the 3D thermal description of liner walls has a great importance for mechanical analysis. Considering the interaction between those 3D solvers, a coupling is necessary to converge on wall temperatures.
