...Bai-Tao An; Jian-Jun Liu; Si-Jing Zhou Multirow film cooling is widely used in gas turbine airfoils cooling to cope with extremely high inlet temperature. The film cooling effectiveness of diffusion slot holes was measured in multirow arrays at a flat plate experimental facility using the pressure...

... of the adiabatic temperature on the heat load of the blades of a gas turbine [ 21 ]. They mentioned that the adiabatic temperature plays a role in determining the heat flux through the air-contact surfaces. On the outer air-contact surfaces, the adjacent local static air pressure can be calculated using...
