Development of software for the thermohydraulic analysis of air coolers [PDF]

Hemijska Industrija, 2003
Air coolers consume much more energy compared to other heat exchangers due to the large fan power required. This is an additional reason to establish reliable methods for the rational design and thermohydraulic analysis of these devices.
