MATHEMATICAL MODELING OF EVAPORATIVE COOLING OF WATER FILMS IN WATER-COOLING TOWERS A. I. Petruchik and S. P. Fisenko UDC 536.42:661.426 A mathematical model of evaporative cooling of water films flowing down vertical guards in a chimney-type water-cooling tower is developed. Results of a qualitative analysis of the nonlinear mathematical model are reported. Data obtained from a numerical solution of a boundary-value problem for a system of ordinary differential equations are presented in the form of graphs. JEPTER7492019998 JEPTER749208
