This paper describes work on a program directed toward assessing the prospects for development of more efficient heat-exchange equipment. Improved equipment leads to more efficient thermal systems and more effective waste-heat recovery. Heat-transfer enhancement is a vital part of this development effort.
Sources of information on heat-transfer enhancement are briefly reviewed. Applications are discussed, with emphasis on those techniques which have made the transition from the laboratory to full-scale industrial equipment. Typical reports of the benefits of enhancement are cited. Factors affecting commercial development and use are also discussed.
