Numerical solution and analytical approximations for flow through a converging-diverging (Laval) nozzle. Initial conditions: Ain=13.2 cm2,Pin=3.5 atm (0.35 MPa),T=293 K,μ=0.002,Min=0.2. (Relative variation of bubble radius, r/rin, is presented as indication for the case of monodisperse spherical bubbles.)
