“…Researchers claimed that optimizing heat transfer surfaces, inducing flow disturbances, and altering flow patterns, can significantly enhance heat transfer rates. The most widely used techniques to accelerate heat transmission rate include the use of vortex generators [ 6 ], inserts [ 7 ], turbulators [ 8 , 9 ], obstructions [ 10 ], cavities [ 11 ], reentrance [ 12 ], converging and diverging areas [ 13 ], magnetic fields [ 14 ], adding nanoparticles [ 15 ], secondary flow [ 16 ], and surface corrugation [ [17] , [18] , [19] ]. These methods are frequently employed either individually or in combination, especially in compact heat exchanger contexts.…”

Previous works that investigated the characteristics of heat transfer and fluid flow in channels with corrugated walls have been extensively reviewed in this study. In accordance with the fast increase in power consumption requirements, many researchers have investigated a new approach for cooling techniques that can enhance the cooling performance of devices without consuming more power. To improve the efficiency of energy systems, many investigators and engineers implement promising techniques such as surface optimization and additives as passive methods to augment the rates of heat transfer. Researchers investigated different corrugation profiles along with various working fluids as well as external power devices to further improve the heat exchange process of thermal systems. The aim of this article is to give a clear preview of the effects of different parameters such as wave parameters, Reynolds number, type of working fluid, and pulsating flow condition on the average and local Nusselt number, the pressure drop, the performance factors, and irreversibility. The main findings are listed in tables and depicted in figures, the matter that helps engineers and researchers to choose a suitable channel shape for their applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
