Numerical Investigation of The Effect of Finned Obstacle on Heat Transfer Characteristics in a Rectangular Channel

Nowadays, with the development of technology and science, heat transfer holds an important place in engineering applications. In industrial areas, increases give rise to overheating, causing system errors. Passive techniques are frequently used prevent from such disruptions. this work, fins which passive provide high efficiency low cost were investigated. To improve transfer, finned structures should be well optimized. On other hand, designer can mixing incoming air heated a bad design, may cause negative effect rather than transfer. contrast previous works that is smooth tube 0 degree rectangular tube, four fin designed flow heat-transfer characteristics numerically analyzed. These crescent 20 symmetrical imperforated asymmetrical perforated banks six rows. investigation, geometric parameters not changed their effects on properties different Reynolds numbers these models examined. The results indicate structure has better transferability higher friction loss compared but overall performance always superior. Therefore, both analyzed highest potential, it seen terms model designs.
