diwakar is on a distinguished road
Hey, i'm working on simulation of gas turbine blade cooling and currently trying to simulate the film cooling in ANSYS Fluent. right now my blade geometry is kinda rough and i have created one internal passage and 3 row of holes on outer surface of blade.

i have attached images to explain my geometry and boundary condition. There's only one outlet for both inlets i.e. inlet for air over the turbine and inlet for flow thorough internal passage. The main problem i'm facing is that air which flows through internal passage is not completely coming out of all film cooling holes, its just coming out of some of the holes. Can anyone plz help ASAP?
