Numerical simulation of film cooling effectiveness with plasma actuator

More Information
  • Dielectric barrier discharge plasma actuation model is established to simulate the flat film cooling process with plasma actuation.The influence of plasma actuation parameters and structure parameters on film cooling effectiveness is analyzed under different blowing ratios.The results show that the increase of actuation voltage,electrode radian and insulation dielectric con-stant or the decrease of electrode thickness and insulation thickness can lead to better coverage on the hot side,thus improving the film cooling effectiveness.The impact of the actuation frequency on the cooling effectiveness is small.The relationship between the cooling effectiveness and the blowing ratio is not affected by actuator parameters.
