Based on the state-of-the art methods of gas turbine cascade heat transfer assessment, a theoretical model of the two-dimensional air turbine cascade is proposed, wherein gas flows past the turbine blade profile. The velocity, temperature, and pressure fields, as well as the heat transfer distribution along the pressure and suction surfaces, the leading and trailing edges of the turbine blade were...
The effect of applying ultrasonic vibration in the ultrasonic compound electrical machining is analyzed. According to the resonance system during machining and on the basis of vibration theory, the shape and dimension parameters of the ultrasonic amplitude transformer and the tool head are calculated and analyzed. The amplitude transformer and the tool head used in this experiment have been designed...
