Analyzes wind effects on cooling efficiency in thermal power plants, suggesting significant performance implications.
The performance of a Heller tower depends on known parameters and environmental conditions such as temperature, relative humidity, wind, etc., so that in addition to temperature and density, the flow rate of air sucked into the tower will affect its efficiency. In windy conditions, due to the disruption of the symmetry of the pressure distribution around the tower and the creation of a capping phenomenon at the top of the tower, the inlet flow rate and efficiency of the cooling tower are reduced, which leads to a decrease in the overall performance of the power plant. In some cases, the effects of crosswinds reduce the cooling efficiency of the NDDCT by more than 27%. In this study, the effects of wind on an NDDCT have been investigated using computational fluid dynamics (CFD). The solution domain has been considered such that the effect of the outlet boundaries on the natural flow of the internal wind is eliminated.
