【Abstract】 Using the nonlinear bubble dynamic equation coupled with the bubbly liquid flow equations, the steady-state solutions for cavitating flows through a converging-diverging nozzle exit are analyzed. It is shown that the flow properties are affected dramatically even through the void fraction in cavitating flow is very small. Cavitation of the cavitating nozzle with converging-diverging exit is stronger.更多还原
