An economical and environmental requirements of hybrid cooling tower in steam power plant are represented by decreasing of outlet water temperature, reducing of water and energy consumption, and working without mist formation. The present work is devoted to study and determine the best contact method of dry and wet tower to build hybrid cooling tower.A three suggested models differs in contacting method of air and water are studied. Analysis of these models are dependent on the basic principles of thermodynamics ,mass and heat transfer with considering of initial and boundary conditions. The best model must be giving accepted values in economical and environmental requirements. A Computer program by Matlab is used for solving the governing equations and determining the suitable mathematical model. The results are indicated that the third model (air in series and water in parallel) is the best in contacting method which satisfied the economic and environment requirements .The results are recorded and represented by graphs.
