摘要: A model equation for describing liquid motion in a foam of polyhedral structure is proposed. dimensionless parameter characterizing the foam, namely, ratio volume energy densities capillary and gravitational forces, introduced. When forces predominate over out-flow process may be regarded as kinematic wave that can described by Burgers equation. In opposite case, absorption quasilinear parabolic
