Characteristics of two-phase flow and heat transfer were numerically investigated in gas injected reactors. Heat transfer characteristic and effects of heat transfer were investigated when temperature of the injected gas is different from that of the liquid. The Eulerian approach was used for the formulation of both the continuous and dispersed phases. The turbulence in the liquid phase was modeled by the use of the standard κ-ε turbulence model. The interphase friction and heat transfer coefficient were calculated by means of correlations available in the literature. The turbulent dispersion of the phases was modeled in introducing a "dispersion Prandtl number". The results in the present research are of interest in the design and operation of a wide variety of material and chemical processes.
