dc.description.abstract	This extensive review aims to provide a thorough understanding of entropy generation (Egen) in confined conduits, or enclosures, by examining a vast array of peer-reviewed research.

The review covers a broad range of studies that investigate Egen in enclosures with diverse geometric configurations and different types of fluids, including air, water, and various types of nanofluids. Furthermore, the review also includes different enclosure structures, such as I, L, C, U, semicircular, triangular, square, rectangular, rhombic, trapezoidal, polygonal, and channel types, as well as wavy wall configurations.

In addition, the review carefully evaluates the validity methods utilized in numerical investigations, incorporating a diverse array of mesh types and sizes utilized in research. A thorough examination of the vast literature demonstrates that enclosures with obstacles, such as single or multiple rotating cylinders, exhibit a noticeable increase in Egen. Also, the review highlights that the use of nanofluids significantly increases Egen. These findings have important practical implications in the analysis of thermofluid systems, including but not limited to heat exchangers, chip cooling, food storage, solar ponds, and nuclear reactor systems. Based on the comprehensive review conducted in this study, several future research directions have been proposed for the emerging field of Egen in enclosures. This study explores the intricate mechanisms of Egen in enclosures and highlights potential avenues for further investigation in this area.

Abstract:

This extensive review aims to provide a thorough understanding of entropy generation (Egen) in confined conduits, or enclosures, by examining a vast array of peer-reviewed research. The review covers various studies on Egen in enclosures with different geometric configurations and highlights the significant effects of thermo-physical dynamics, such as temperature gradient, viscous dissipation, frictional drag, and magnetic field strength, on Egen characterization. The review covers a broad range of studies that investigate Egen in enclosures with diverse geometric configurations and different types of fluids, including air, water, and various types of nanofluids. Furthermore, the review also includes different enclosure structures, such as I, L, C, U, semicircular, triangular, square, rectangular, rhombic, trapezoidal, polygonal, and channel types, as well as wavy wall configurations. Notably, the review also encompasses both 2D and 3D cases to present a complete comprehension of Egen in confined conduits. In addition, the review carefully evaluates the validity methods utilized in numerical investigations, incorporating a diverse array of mesh types and sizes utilized in research. A thorough examination of the vast literature demonstrates that enclosures with obstacles, such as single or multiple rotating cylinders, exhibit a noticeable increase in Egen. Also, the review highlights that the use of nanofluids significantly increases Egen. These findings have important practical implications in the analysis of thermofluid systems, including but not limited to heat exchangers, chip cooling, food storage, solar ponds, and nuclear reactor systems. Based on the comprehensive review conducted in this study, several future research directions have been proposed for the emerging field of Egen in enclosures. This study explores the intricate mechanisms of Egen in enclosures and highlights potential avenues for further investigation in this area. These insights will contribute to the advancement of the knowledge base and practical applications of thermofluid systems, including heat exchangers, chip cooling, food storage, solar ponds, and nuclear reactor systems.
