“…The effective eddy diffusivity is derived from energy balance. In the energy balance for the calculation of liquid velocities of a continuous two‐phase flow, the total viscosity consists of molecular viscosity, eddy viscosity in the single‐phase flow, and additional turbulence viscosity in the presence of bubble and we can summarize the last two components,

- ɛ_{g} u_{normalT} - \frac{ɛ_{normalg} u_{normall}}{1 - ɛ_{normalg}}

, where the sign will be positive if the liquid is counterclockwise, as interphase dissipation and the energy supplied by pump. The relationship among these energies significantly influences the liquid circulation velocity, circulation cells, and local gas holdup.…”
