Mathematical Modeling of Hybrid Cooling Tower for Steam Power Plant

Abstract

An economical and environmental requirements of hybrid cooling tower insteam 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 dryand wet tower to build hybrid cooling tower.A three suggested models differs incontacting method of air and water are studied. Analysis of these models aredependent on the basic principles of thermodynamics ,mass and heat transfer withconsidering of initial and boundary conditions. The best model must be givingaccepted values in economical and environmental requirements. A Computerprogram by Matlab is used for solving the governing equations and determining thesuitable mathematical model. The results are indicated that the third model (air inseries and water in parallel) is the best in contacting method which satisfied theeconomic and environment requirements .The results are recorded and representedby graphs.
