摘要：

Basic parameters of a double-pipe enclosed heat exchanger were calculated for four possible cases of ideal heat-carrier flow structures. It was shown that the heat-transfer coefficient depended little on the ideal heat-carrier flow structures although the heat-transfer driving force and specific thermal power changed by a factor of three. Technological and geometrical parameters from a typical calculation of a double-pipe enclosed heat exchanger with plug flow of both heat carriers without and with temperature jumps at the heat-exchanger inlet were compared. © 2017, Springer Science+Business Media, LLC.
