00-06: A New Look at Recirculation Analysis Including Measure of a 50 Cell

The Bang-Pakong cooling tower in Thailand was designed to cool 1.8 Million GPM of water. The cooling tower had 74 cells arranged in 6 modules along the river. Four of these modules, arranged in two rows, were closed one to the others. Such layout provides recirculation effect. The paper presents the recirculation measurements, the recirculation thermal effect on performance and some guidelines for cooling tower design taking their circulation into consideration.
