Heat Transfer

Use CFD analysis to evaluate the impact of hot air recirculation on air-cooled heat exchangers

Chen, C-C., CTCI, Corp.

Air-cooled heat exchangers are widely used in the petroleum, petrochemical, natural gas and other industries for cooling purposes. In contrast to a water-cooled system, which consists of a traditional shell-and-tube heat exchanger and a cooling tower, an air-cooled heat exchanger uses ambient air as the main cooling medium.
