摘要
In this paper, a laminar mist/air slot jet impingement has been considered to enhance the heat transfer rate from an isothermal target flat plate surface. The droplets are modeled as heat sinks, dispersed in the continuous gas phase and the governing equations for two-phase gas-vapor-droplet flow have been solved numerically. The effect of thermal and flow parameters such as the Reynolds number, target temperature, droplet size, and mass concentration of the liquid phase on local heat transfer rate of the region near impingement has been determined. The results obtained indicate that by adding a relatively low mass concentration of liquid droplets, the rate of heat transfer in mist/air impingement jet enhances drastically.
