The International Journal of Heat Exchangers (IJHEX) disseminates original research relating to all aspects and types of heat exchangers. IJHEX provides an important independent forum for those engaged in basic and applied heat exchanger or related research at universities and industry throughout the world. The journal is devoted to fundamental investigations of transport of momentum and heat and other thermal and hydraulic phenomena, including theoretical-numerical modeling and experimental techniques. Papers on new developments, applied topics, mechanical problems, and other general technical and scientific issues related to design, materials, manufacturing, and operation of heat exchangers are also considered. All papers are reviewed.
