Recent development of combined heat transfer performance for engine systems: A comprehensive review

Abstract

Heat transfer regulation between engine components has a direct impact on engine efficiency and performance. Improving engine system efficiency, reducing emissions, and prolonging component life all depend on efficient heat management. This review looks at recent advancements in integrated heat transfer optimization to boost efficiency, reduce emissions, and improve engine system performance. This effort also investigates producing intricate heat transfer components with improved geometry using additive manufacturing techniques. With additive printing, designers may more easily construct complex structures and optimize heat transfer surfaces for better performance. The development of nanofluids and nanocoatings now allows for improving heat transfer qualities. Nanotechnology advancements have made this possible, and nanostructured materials' enhanced surface properties as well as thermal conductivity contribute to better heat dissipation in engine systems. The modern automotive and aerospace sectors have high standards, which are met through novel designs, materials, computational tools, and integrated cooling systems. Additionally, these improvements pave the way for more efficient and environmentally friendly engine operation. Because of the integration of computational technologies like numerical modeling and CFD, engineers can now see complex heat flow patterns and construct more efficient cooling solutions. Additive manufacturing has changed component manufacturing by enabling sophisticated designs that maximize heat transfer surfaces.
