The article deals with the development of one of the key part of the complex CFD model of natural draft wet-cooling tower flow namely model of rain zone. The physical phenomena occurring in the natural draft cooling tower can be described by the combined Eulerian-Lagrangian model with additional model of film type fill. The Eulerian part is the model of the flow of homogeneous mixture of dry air and water vapour. The Lagrangian part is the model of transport of liquid water droplets. The heat and mass transfer between Lagrangian phase and Eulerian phase is included via source terms in the model of homogeneous mixture of dry air and water vapour. The simplified model of rain zone based on the solution of boundary value problem for the system of ordinary differential equation is also derived.
