A Modified Method of the Number of Transfer Units for Calculating a Cooling Tower

Abstract

Calculation of a cooling tower with regular packing using a modified method of the number of transfer units is considered. Diffusion models recorded for gas and liquid phases with volumetric sources of mass and heat, taking into account interphase transfer, are used to account for the mixing of flows. From the solution of diffusion models, unknown coefficients are identified from the number of transfer units. A sample calculation of the layout of a cooling tower with plastic mesh packing is given along with experimental values of the regime and the thermodynamic parameters of water cooling in the cooling tower.
