Abstract
A theoretical study based on a new foam-flow model in which the viscou s effect occurring in the flow of a foam is taken into account is pres ented. It is found that the deformation of foam bubbles gives rise to interface stresses. The values of components of the strain and interfa ce-stress tensors are obtained. A relation between the flow rate of a foam and its rheological and structural parameters with regard to the redistribution of the liquid-phase body over the channel section is pr oposed.
