Riemann problem when modeling dual-speed bubble flow

The effect of the fluctuating components of stress tensor of the carried phase on the wave properties of the system of averaged equations of a gas-liquid flow with incompressible phases is considered. It is shown that the characteristic properties of this system and also the possibility of modeling the Zuber-Findlay empirical relation , movement of suction wave and rupture are determined by the tensor of fluctuating stresses of the carrier component.
