SINOPSIS

In design of air coolers, using heat transfer enhancement techniques not only causes reducing the size of surface area required for a certain duty but can also help to remove some operational problems such as fouling and blockages due to limitations on pour point and solidification of fluids inside of tubes. For accomplishing the previous studies on application of heat transfer enhancement using tube inserts that have been done by the authors, in this paper, the comparison between the fan power requirement of plain and enhanced air coolers for achieving the optimized air side heat transfer coefficient will be presented. The mentioned factors will affect the total cost of design of an air cooler.
