An algorithm for cost comparison of optimized shell-and-tube west exchangers with tube inserts and plain tubes

Heat transfer enhancement is currently allocated the most part of investiga tions to improve the thermal performance of shell and tube heat exchangers. Here an algorithm for cost comparison of an optimized enhanced tube heat e xchanger to an optimized plain tubes has been developed. The results are sh own in plots which allow the engineers to compare directly the capital cost of heat exchangers and to select the better options among the various tube inserts for a given duty.
