Review on Heat Transfer Enhancement Techniques in Heat Exchanger

Heat exchangers are crucial components in various industrial processes and energy systems, facilitating the efficient exchange of thermal energy between fluids. To optimize their performance, researchers and engineers have developed and explored numerous heat transfer enhancement techniques. This abstract provides a concise overview of these techniques, which include passive and active methods. Passive techniques involve the use of enhanced surfaces, geometrical modifications, and advanced materials to augment heat transfer. Active techniques employ external mechanisms like mechanical agitation, pulsating flow, and fluid additives to enhance thermal performance. This abstract summarizes the key principles and benefits of these methods, highlighting their potential to improve heat exchanger efficiency, reduce energy consumption, and minimize environmental impact. Moreover, it underscores the importance of selecting the most suitable technique based on specific application requirements. A better understanding of these techniques will aid engineers and researchers in designing more efficient heat exchangers and addressing the ever-growing demand for enhanced heat transfer solutions in various industries. An effort has been made in this paper to review the literature related to the heat exchangers and heat transfer enhancement techniques to improve the efficiencies of heat exchangers.
