Abstract:
Response of turbine flow meter in a vertical air-water two-phase flow is experimentally investigated. The flow field and the transient response of turbine are captured through a high speed camera, and the cross-sectional phase distribution is recorded by arrayed ERT. The experiment reveals that the rotational rate of the turbine drops when air intrudes into the rotor, and the relative fluctuation amplitude of the rotation decreases with the water flow. For the benefit of combined flow measurement with ERT and turbine meter, an extension to TG turbine performance model involving the non-steady two-phase effects is implemented. It is found that, given the ERT phase information, the extended model may well depict the response of turbine flowmeter in two-phase vertical flow.
