Design and performance analysis of curved fins with convex inner flow surface

Investigated in this paper are performances of radiator. We try to increase the radiator performance. How we are increased the performance means, tochange the radiator fin surface. The radiator fin surface is always straight-line surface, but we changed the curved surface. Generally, fin surface to transfer the heat, but we are increased the more heat transferred. Our project is to improve the performance of radiator. Performance of radiator can be increased by increasing the surface area exposed to heat transfer, increase the overall performance of the radiator by reducing the frontal area, optimizing design aerodynamically, and by many ways. In this project the surface area of the fin element subjected to heat transfer was increased by us. and along the longitudinal axis to achieve Coanda effect, the fin aerodynamically convex curve had been designed by us. The increase in surface area exposed to heat transfer reduces the frontal area of the radiator, which in turn reduces the aerodynamic drag this will increase the overall efficiency. The convex internal flow surface was designed by us in such a way to achieve Coanda effect so that the air fluid gets adhesion to the internal flow region of the curved radiator fin. Coanda effect is the tendency of a fluid jet to stay attached to a convex surface. Thus, by achieving Coanda effect in our design, the size of the radiator can be reduced and the effectiveness of the fin can be increased.
