An investigation is to be conducted to determine whether protrusion on a fin can increase heat transfer under forced convections or not. This would be accomplished by performing an experimental investigation. This research investigates new fin topologies with heat transfer characteristics that will surpass conventional fin, where the main goals are to increase the heat transfer rate of the fin surface while keeping an acceptable pressure drop penalty. Boundary layer regeneration and enhanced

Surface roughness is usually applied to smooth surfaces to promote flow mixing and initiate turbulence in the flow. In this experiment the radiation factor is neglected. Increasing the temperature difference between the object and the environment, increasing the convection heat transfer coefficient, or increasing the surface area of the object increases the heat transfer. Sometimes it is not economical or it is not feasible to change the first two options. Adding a fin to an object, however, increases the surface area and can sometimes be an economical solution to heat transfer problems.
