Air film cooling as a conventional cooling technique has been successfully used with gas turbine hot-section components, such as combustor liners, combustor transition pieces, and turbine vanes and blades. However, the increased benefits seem to approach their limit. This paper investigates the film cooling effectiveness in consideration of the mist injection. All the studies with various boundary conditions are conducted numerically, including effects of the droplet size, the flow rates of droplet injection and the coolant air. Film cooling is also affected by the interaction between the deposition and the mist injection. There is a deposition configuration near the film hole with an inclination angle of 35º. Results show that the combined effect of the injection and the deposition weakens the film cooling effectiveness especially before x/d = 19. For the coolant air at a low speed, the mist injection cannot provide a better cooling protection than that without the mist injection.
