Fins are used to increase the rate of heat transfer to or from the environment by providing excess surface area. Fins performance can be increased by reducing perimeter by area ratio, using material with high coefficient of thermal conductivity(K) and by optimizing size and distance between fins over surface. Boundary layer generation over fin also effects heat loss widely. If boundary layer(BL) of one fin intersects BL generated from other fin then fin performance reduces. Same concept is also applicable on Macro-fins. In our paper we simulated thermodynamic boundary layer over Bell shaped fins (Gaussian distribution) and used these fins to model increase in heat transfer with surface roughness
