Interphase momentum exchange

In order to clarify interphase momentum exchange terms, the case of two-phase flow is considered below. Let phase 1 be a continuous phase and phase 2 a dispersed phase. The interphase exchange force exerted in the i direction on the dispersed phase (phase 2) by the continuous phase can be modeled as... 

The mesoscale interphase momentum-exchange terms are typically written in terms of the velocity difference (Vp - Vf). Thus, in the simplest cases, in which these terms are linear in the velocity difference, the second-order moment-transport equations in Eqs. (4.109) and (4.116) will contain source terms involving the following mixed moments ... 

The interphase momentum exchange between gas-liquid and liquid-solid phases and vice versa is... 

Thus, as was shown in Ref. 2, for characteristic specimen thicknesses over 50 mm the effect of interphase momentum exchange can be neglected this means that the medium can be described as a one-fluid, two-temperature... 

The Eulerian multiphase model is used to predict the dispersed gas-liquid flow in the airlift loop reactor. It involves a set of momentum and continuity equations for each phase. Model equation coupling is achieved through the pressure and interphase exchange coefBcdents [5],...
