Methods and Developments for Enhancement of Heat Transfer

Dear Colleagues,

Owing to the demand for the miniaturization of heat exchange devices, heat transfer enhancement is extremely important nowadays for the requirement of transporting heat at a greater rate to improve the heat transfer performance. There are many aspects directly involved in augmenting heat transfer, such as fins and microfins, porous media, large particles suspensions, nanofluids, phase-change devices, flexible seals, flexible complex seals, vortex generators, protrusions, and ultra-high thermal conductivity composite materials. Among these, fins and microfins are widely used in enhancing heat transfer by considering the porous medium, helical shape, array arrangement, joint type, capsulated liquid metal, permeable condition, biconvection, and root effect. Nanofluids are now used for the enhancement of heat transfer by establishing the reasons for augmentations. The flow and heat transfer in porous media is a passive model for the enhancement method. Helping the system support based on flexible/flexible–complex seals is a wide scope to deal with the enhanced heat transfer is possible. Other methods, such as vortex generators, protrusions, and composite material with ultra-high thermal conductivity, participate in passive augmentations of heat transfer. For each enhancer, the enchantment factors are the primary parameter to evaluate the augmentation characteristics.         

The main purpose of this Special Issue is to collect the latest findings of outstanding research on the enhancement of heat transfer, focussing on state-of-the-art progress, methods, developments, and new trends.
