| Abstract: | The size distribution,motion behaviours and deposition positions of the coarse water droplets in the diaphragm of wet steam turbines were calculated and analysed.Using a two-phase flow test rig with air-water film flow on a plate,the effects of flow parameters on the motion pattern of the deposited liquid were investigated and the correlations of moisture-removal rate of suction slit with the slit width,suction pressure drop,interfacial shear stress and film Reynolds number were determined. |
