Abstract

At the moment, there is a lot of focus on how to make cross flow heat exchangers operate better. In this study, we use the computational fluid dynamics (CFD) programme to conduct a numerical study of a cross-flow heat exchanger in ANSYS Fluent. A heat exchanger with a dimple on its fine surface will work better. To model and statistically examine the impact of spherical dimples on the heat exchanger's performance, we used a cross flow heat exchanger. Attaching the smooth fin plate and fin holes was the subject of numerical research for varying fin areas and fin hole densities. We used an intake air temperature of 299.45 K and a constant tube surface temperature as our boundary conditions. In order to get the best possible outcome, it was necessary to evaluate the temperature effectiveness, fin plate temperature, outlet temperature, and heat transfer enhancement balance. Case 6 having maximum outlet temperature and temperature effectiveness which is 303.421 K, and 13.835% respectively. Due to heat transfer between air and fin plate temperature of fin plate is minimum in case 6 and maximum in case 1 which is 319.048 K, and 319.628 K respectively.
