... to the lower phase and vice versa. The simplified formulation for heat transport derived by Hsieh (1972, “The Effect of Heat and Mass on Rayleigh Taylor Instability,” ASME J. Basic Eng., 94 (1), pp. 156–160) is utilized here. In the perturbed state, the mathematical equations are linearized and the well-known...

.... In the future, for cavitating pumps, the results of this study can be used to theoretically estimate the volume of backflow-vortex cavitation and predict flow instabilities, such as oscillating flows and surges, using the theories of the mass flow gain factor and cavitation compliance [ 20 ]. For compressors...

... growth rate of the sinuous disturbance wave is greater than that of the varicose one. A similar conclusion was researched previously [ 21–23 ]. Therefore, the instability of liquid sheet occurs in the dominant sinuous disturbance wave. For this reason, only the sinuous disturbance wave is investigated...
