Resumen
DU PREEZ, A. F. y KROGER, D. G.. Experimental investigation into the influence of cross-winds on the performance of dry-cooling towers. R&D j. (Matieland, Online) [online]. 1993, vol.9, pp.1-11. ISSN 2309-8988.
Relatively little information is available in the literature quantifying the effect of cross-winds on the heat rejection rate of natural draft dry-cooling towers. In this study a series of tests are performed on a scale model of a circular natural draft dry-cooling tower with the heat exchangers arranged in a horizontal pattern (not A-frames) over the entire inlet cross-section of the tower. The effect of the wind on such towers is found to be complex and is influenced by a number of parameters including the wind velocity, the shape of the approaching wind profile, the heat exchanger and support pressure loss coefficients, the shape of the tower shell, the inlet diameter to inlet height ratio of the tower, the tower height and the heat rejection rate of the tower. Further reductions in the heat rejection rate of the tower are caused by a non-uniform air temperature distribution inside the tower and flow distortions through the heat exchangers.
