acomparsion between the counter and crow flow cooling tower for the rmal power plants

In this paper the counter flow cooling tower in Al-Nassiriah thermal power station was studied . Design of new cross flow cooling tower is made and tested instead of existing counter flow cooling tower . The analysis of cross flow cooling tower is made by using finite difference method. The design parameters of the cooling tower are evaluated at different operating conditions such as variations of weather , different water to air flow ratio. Then comparison between the results of two tower types shows that the cross flow cooling tower has high performance in heat transfer process. A computer program is developed to make the necessary design computations for both types of towers to evaluate the variation with the different conditions.
