Sažetak
In order to improve film cooling effectiveness, plasma actuator is arranged on blade surface in this research. As one novel device based on active flow control, plasma actuators have many advantages, such as fast response, small volume and low power consumption. Due to plasma aerodynamic actuation, the blade temperature decreases significantly. This paper investigated an effect of arrangements of plasma actuators on film cooling performance. Results show that the film cooling effectiveness is improved significantly when the plasma is applied to the wall surface. It is found that the maximum increment of the average wall film cooling effectiveness is 11.7% at low blowing ratios compared with plasma off (PA-off), when the actuator is arranged near the outlet of the film cooling hole (PA-up). Compared with the PA-off case, the average wall film cooling effectivenesses of the PA-down case and PA-both cases increase by 138.3% and 122.9% respectively.
