The Effect of Micro-Scratches on steady and transient heat transfer through surface of Circular Fins

 Nidhi Yadav from semester 4, MTech Mechanical engineering, has simulated the system that analyses the surface smoothness of the fins used in various heat transfer applications as electronic cooling systems, heat exchangers, and air conditioning units are analysed for heat transfer characteristics. Finite element anaysis is used to study the losses due to scratches on the surface. Such study helos in investigating the material losses due to heat. Figure shows the simulation of the surface smoothness.
