Abstract

The internal turbine mechanism is a new sensor that can be used for independent velocity measurement of underwater high speed moving body. It is a meaningful study when the cavitation flow field around and trajectory changes of the high speed moving body was taken into consideration. The parameterization of turbine mechanism was done at first. Then the surrounding flow field was analyzed and the CFD simulation model was established. The cavitation tunnel experiment was done at speed of 0~10m/s with cavitation number minimum to 0.2. On this basis, an overall analysis of the sensor characteristics was done by CFD simulation results in different situation at speed of 0~100m/s. Compared with sensor characteristics of traditional turbine measuring mechanism, this turbine mechanism has many different sensor characteristics and a wide velocity measurement range of 5m/s~70m/s.
