CFD Analysis to Analyze Thermal Characteristics of a Heat Exchanger Handling Combination of Dimple Ribs

It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.
