The measurement lower limit of traditional turbine flowmeter is too large to satisfy the measurement requirements of small flow rate. A modified optical fiber turbine flowmeter based on the traditional turbine flowmeter principle was purposed. The front guide vane was specially designed with a helix angle to reduce the measurement lower limit and improve the measurement sensitivity. The theoretical model for the modified flowmeter was established based on planar vector triangle of flow velocities. From theoretical analysis, the conclusion that if the helix angle of front guide vane plus the helix angle of turbine equals to 90°, the starting volume flow rate of turbine can get minimum value and the sensitivity of the flowmeter can get maximum value was found. The correctness of the conclusion was verified by the Computational Fluid Dynamics (CFD) simulation.

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.

This paper gives a numerical simulation to research the turbine flowmeter at starting flow by ANSYS 12.1 and verifies the accuracy of the simulation by experimental method. And it is found that the simulation method is reasonable for the investigation and can be used for improving the performance of turbine flowmeter at low flow rate. Finally, the consequence of the gap between the blade tip and shell is discussed.
