Abstract：
Sets up a heat and mass transfer mathematical model for both parallel and counter flow type closed cooling towers. Calculates the model by fourth order Runge-Kutta numerical method and compares the results with those from experiment. Simulates and analyses the distributions of cooling water temperature, spray water temperature and air enthalpy.
