Abstract

The influence of flow rotation in the overshower zone of a natural draft wet cooling tower NDCT on heat and mass transfer in this zone is investigated numerically The 3D geometry of an actual NDCT and three models of the induced rotation velocity fields are utilized for calculations Two phases liquid and gaseous and three components are taken into consideration The interphase heat exchange heat transfer to the walls condensation–evaporation intensity field and other parameters are investigated as functions of the induced rotation intensity the inclination of the velocity vector at the periphery It is shown that the induced flow rotation intensifies the heat and mass transfer in the overshower zone of an NDCT Flow rotation leads to specific redistribution of evaporation–condensation areas in an NDCT and stimulates water condensation near its walls
