摘      要：This paper presents the experimental and numerical results of the bubble detachment from a submerged orifice at a constant gas flow *** compressible large eddy simulation combined with the volume of fluid method is adopted in the simulation and is validated by *** transition criterion from the elongation stage to the detachment is *** the detaching stage in the simulation,the distributions of the pressure and the surface tension on the cylindrical bubble neck are *** Rayleigh-Plesset equation in the cylindrical coordinate frame is used to describe this *** on the comparison between the numerical results and the equation analysis,a reference value of the uncertain integral parameter in the equation is determined.
