The influence of wind on the performance of forced draught air-cooled heat exchangers

The influence of wind on fan performance and recirculation in a forced draught air-cooled heat exchanger (ACHE) bank is investigated numerically. Winds blowing across and parallel to the longitudinal axis (long axis) of an ACHE bank are considered. It is found that cross winds significantly reduce t...

Summary:The influence of wind on fan performance and recirculation in a forced draught air-cooled heat exchanger (ACHE) bank is investigated numerically. Winds blowing across and parallel to the longitudinal axis (long axis) of an ACHE bank are considered. It is found that cross winds significantly reduce the air volume flow rate that is delivered by the up-wind fans, while winds along the longitudinal axis cause increased hot plume air recirculation along the sides of the ACHE bank.
