Abstract
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.
