Abstract:
The results of a numerical study of heat transfer in a gas-droplet turbulent flow behind a single square barrier with variations in the initial mass concentration and diameter of dispersed phase particles are presented. When flowing around a barrier, adding droplets to the flow leads to a significant intensification of heat transfer (almost twice) compared to a single-phase air flow. It is shown that when a two-phase flow flows around a transverse barrier, the coordinates of the maximum heat transfer intensity and the flow reattachment point differ by approximately 12%. An increase in the barrier height leads to a decrease in heat transfer intensity.
