Abstract:
In order to study the disintegrated process of a viscous liquid jet moving in an incompressible gas medium,a linear stability analysis was carried out using the linearized Navier-Stokes equations, the linearized kinematic and dynamic boundary conditions,and employing the stream function method.The results indicate that:the dimensionless dispersion relation of the zero-order varicose waves in circular liquid jets can be derivated,which is related to some dimensionless parameters,they are Weber number We; Reynolds number Re; Euler number Eu; Mach number Ma, gas-liquid velocity ratio U and gas-liquid pressure ratio P. 2 figs, 6 refs.
