“…This is lead to poor in ACC performance of AF. [24] Also found that by volumetric flow variation there is the inlet temperature for the for the condenser cells at the both sides of the middle or downstream rows is slightly higher than that in the center of those rows. Its shows the hot plume recirculation flows arise at the both sides of the middle rows.…”

“…Royen and Kroger [18] agree with the conclusion that increase in inlet air temperature at both sides is deteriorated the thermo flow performance of air cooled condenser are mainly affected from the wind induced volumetric flow rate of AF decrease, but not the hot plume recirculation. And it is clear that wind direction 90 0 results in deficiencies in the thermo-flow performance for ACC AF [24].…”

Abstract. It is of benefit to the efficiency improvement of direct dry cooling generating units to investigate the operation adjustment approach of axial flow fans. On the basis of a 2×600MW direct dry cooling power plant, thermo-flow performances of the generating units at various wind speeds and directions are obtained by means of CFD method. It is found that an increase in rotational speed of the upwind axial flow fans in the first row will result in a decrease in the net power output. However, it will increase when the rational speed of all axial flow fans except the axial flow fans in the first row is raised. Finally, elevating the rotational speed of all axial flow fans will result in an improvement of net output at low wind speeds but a decrease at high wind speeds.

“…This blockage can lead to a high inlet air temperature at the nearby radiators and consequently a sharp decrease in the cooling capacity of air at high wind speeds. Yang et al 6 . also indicated that the wind effect decays rapidly along the wind direction due to the combined behavior of hot plume discharge and ambient wind.…”

The use of air-cooled condenser (ACC) has become very popular in erecting thermal powerplants around the world since two or three decades ago. The advantages of forced convection heat cooling system, instead of the classical natural draught convection heat transfer cooling systems, promote the thermal powerplant designers and users to benefit more from such systems in their thermodynamics cycles. However, such forced convection heat transfer mechanisms, can lose their cooling efficiency in off-design ambient conditions, i.e., in high wind velocity and high ambient temperature conditions. There have already been some efforts to analyze the reduction of ACC System performance in some critical ambient conditions. This work presents a detail investigation on the performance of an ACC in real conditions of an existing powerplant. We use the computational fluid dynamics CFD tool and quantify the detail performance of the ACC system in different wind velocities and ambient temperature conditions.
