Heat Transfer Enhancement and Fluid Flow Features Due to the Addition of Nanoparticles in Engineering Applications

Dear Colleagues,

Heat transfer is vital in many processes, including electric power generation, automotive propulsion and climate-control systems, household heating and cooling equipment, control of body temperature through clothing, thermal management of electronic equipment, and Earth–atmosphere systems, to name a few examples. Whenever there is a temperature difference, there is heat transfer. Therefore, heat transfer enhancement has become a necessity due to the development of modern technology, with heat exchangers required in various industries for high heat-flux cooling to the level of megawatt per square meter. Enhancement of convective heat transfer is one of the fastest-growing areas in heat transfer. Techniques for enhancing convective heat transfer include passive techniques such as treated surfaces, rough surfaces, extended surfaces, displaced enhancement devices, swirl-flow devices, coiled tubes, surface-tension devices, and additives for fluids such as nanoparticles. Some researchers add only one type of nanoparticles to the base fluid, whereas others are adding two. Examples of active techniques include mechanical aids, surface vibration, fluid vibration, electrostatic fields, suction or injection, jet impingement, compound techniques, and use of a rough-surface tube with a twisted-tape insert. Many other possibilities exist when two or more techniques are combined, an approach termed compound enhancement. Hence, the objective of the Special Issue is to present recent advances as well as up-to-date progress in all areas of heat transfer due to the addition of different types of nanoparticles in engineering and its influence on emerging technologies.

The broad topics of interest include, but are not limited to, the following:

• Heat transfer and thermal phenomena at all scales (from nanoscale to macroscale)
• Thermal systems and thermal management systems
• Nanofluids, hybrid nanofluids and fluid additives
• Interdisciplinary study focusing on heat transfer
• Waste heat recovery and allied heat transfer applications
• Heat transfer in energy storage and energy conservation
• Experimental, numerical, and analytical studies focusing on heat transfer and thermal phenomena
• Fundamental mechanism and practical applications of heat transfer in wide variety of processes
• Heat and mass transfer
