The entrainment of hot moist air from a cooling tower into the tower inlet air decreases both overall tower and plant performance. This study characterizes recirculation on a circular mechanical draft-cooling tower. Data taken on this tower are compared to data from similar tests on rectangular mechanical draft cooling towers in this paper.
