SINOPSIS

Direct numerical simulation has been carried out for non-isothermal turbulent upward channel flow with four immiscible droplets whose density is higher than that of continuous-phase flow. The interface was tracked by the modified volume-of-fluid method. The computational results show that both the outward flow in the wake and the wallward flow around the cap of a droplet enhance heat transfer. These flows are attenuated by the adjacent droplet in the axial direction. The droplets prevent the evolution of hairpin vortices and attenuate the developed vortices.
