Abstract
In the present paper, thermal conductivities of different plate materials were numerically studied by investigating the film cooling characteristics and the fluid field above the plate. The heat flux was also studied, and the optimal blowing ratio was given. It's found that the velocity ratio of 0.5 shows the more uniform and more stable cooling effectiveness. In addition, compared with the film cooling, the thermal conductivity plays an important role on the wall cooling effectiveness.
