Heat transfer enhancement of three types of tubular oil cooler

transversally finned tube bundle supported with segmental baffles

petal - form fin tube bundle supported with segmental baffles and with nests constructed with wave form long holes has been experimentally investigated. The results of evaluation of heat transfer performance of these oil coolers show that petal - form fin tubes can enhance heat transfer more effectively than transversally finned tubes and longitudinal flow in shell side with nest supports is better than cross flow with segmental baffle supports.
