Active Techniques of Heat Transfer Enhancement: A review

Abstract

In this work, active methods for improving heat transfer are discussed, with a particular emphasis on new ideas and their applicability in various sectors of different types. Heat transfer efficiency is essential for optimising energy utilisation in industries such as chemical processing, heating, ventilation, air conditioning (HVAC), and renewable energy. Mechanical assistance, surface vibrations, electrostatic fields, and fluid injection are some approaches investigated in this research. The study also investigates the ideas behind these techniques and their practical ramifications. The results of this study indicate that active approaches, even though they often call for more power, have the potential to greatly improve thermal performance and provide new solutions for difficult technical difficulties.
