Theoretical assessment of evaporation rate of isolated water drop under the conditions of cooling tower of thermal power plant

The purpose of the work is numerical modelling of heat and mass transfer at evaporation of water drops under the conditions which are typical for a modern chimney-type cooling tower of a thermal power plant. The dual task of heat and mass transfer with movable boundary at convective cooling and evap...
