ResumoCooling towers operating in western Canada are often subject to adverse weather, which can hinder their performance. In particular, during the winter months, cooling towers may experience strong winds and sub-freezing temperatures. This condition often leads to ice formation at the windward intake. The purpose of this study was to quantify the effect of wind on the air flow through a cooling tower. A 1:25 scale model of a counter flow cooling tower was tested in the simulated atmospheric boundary layer of a wind tunnel. The external flow patterns, pressure characteristics and intake flow rates were documented. These results indicate that winds strongly influence the flow entering the tower, especially the flow through the windward intake which increased by as much as 45%.
