An experimental measurement was performed of the three-dimensional average speed in the flow field of an air-cooled annular turbine cascade by using LDV method to study the impact of hole jet flow on the flow field in an annular turbine cascade.

Four different turbulence models were applied to simulate three-dimensional flow field in annular turbine cascade with film cooling.

This paper discusses the structure type and design features of GTH resistant ring type silencer with the view of ring type flow passage as the deformation of rectangular one.

Based on the principle of traveling wave ultrasonic motor and the results of the Finite Element Method analysis, a new kind of ring type traveling wave ultrasonic motor which is the smallest one in the same type in China has been designed and fabricated.
