Transient and Steady state heat transfer simulation is carried out on the engine. A two wheeler bike engine is chosen (e.g. Unicorn bike engine) and geometry is designed in Design Modeller in Ansys 16.0. Material used for is Al 6063 which has a thermal conductivity of 200 W/m K. A modification in design of engine is made by creating holes on fin, various diameters 2mm, 6mm & 10mm holes on fin have been considered. In addition, a perforated fin was compared with an imperforate fin to observe the differences.It is observed from the results that before a time period of 400 seconds Transient minimum heat flux of all fins has not reached to steady state. However, Fin with a hole of 2mm & 10mm dia has reached the steady state limits before a time period of 100 seconds when compared with other fins.
