results and production experience, combined with the international advanced technology of similar products, developed high efficiency and energy saving products, usually used for pumping no solid particles, insoluble in water, no corrosion gas, in o...
while the values of dilatation are high in the cavity region and increase with the decreasing NPSHa. Even though the magnitude of the baroclinic torque term is smaller than vortex stretching and dilatation terms, it is important for the vorticity...
