Heat Transfer Reinforcement Techniques in Heat Exchangers

Dear Colleagues,

Improving the thermal and dynamic performance of heat exchanger and solar collector channels is the goal of many numerical, analytical, and experimental studies in the field of renewable energies. Several methods have been followed for successful energy efficiency, such as restructuring the internal structure of the channel by adding extended surfaces or improving the thermal physical properties of the flow by creating new fluids, such as nanofluids. These energetic enhancement strategies are essential and have been the target of many recent studies. Several recent review studies have summarized various research related to promoting heat transfer and its applications with channels using baffle and fin-type obstacles. Various research studies have examined different types of turbulators, deflectors, and vortex generators for different flow conditions. On the other hand, nanofluids have witnessed significant development during the recent period by improving its structure, in addition to its multiple applications in various industrial fields. Many review analyses have dealt with the latest events of these fluids in terms of composition, as well as in terms of their use. In addition, the application of nanofluids has not only promoted heat transfer in the channels but was also used for other configurations, such as cavities and enclosures.

This Special Issue aims to seek and promote knowledge on the technology and science of heat-exchanger energy and its applications. Original research papers and reviews on the various topics of heat transfer systems and components are welcome. Papers of experimental aspect, numerical simulation and modeling are welcome. Topics of interest for the Special Issue include, but are not limited to, the following: models and applications of heat exchangers; heat transfer enhancement techniques (vortex generators, nanofluids, porous media, etc.); heat and mass transfer; fluid–solid interactions; modeling, simulation, optimization, experimentation, and characterization of heat exchangers.
