A numerical study of the process of interphase mass transfer during the motion of a gas bubble at different inclination angles in case of movement in the channel between the layers of gel is presented. The dependence of the effective dimensionless mass transfer coefficient depending on the angle of inclination of the channel was obtained. The relation between effective dimensionless mass transfer coefficient and the speed of the freely rising gas bubble was found. A new exact method for solving 3D systems of hydrodynamic equations is described based on decomposing these systems into simpler equations. It is obtained that the exact solution to a 3D nonstationary system of the Navier–Stokes equations can be expressed in terms of two stream functions.
