Providing more amount of heat transfer may supply possibilities for size reduction in engine parts specifically the engine water jacket that is of concentration for the present study. Boiling phenomenon, by providing more amounts of heat transfer in comparison with single-phase, provides conditions for size reduction. In this paper an experimental correlation has been introduced in order to model boiling effect in a gasoline engine. In this work effects of boiling have been considered through calculation of the coolant convection coefficient. The introduced correlation and the method have been used to simulate thermal behaviour of the coolant within water jacket of a gasoline engine. Data show that the proposed model has good accuracy and it can be employed in designing procedure. Finally the onset of boiling phenomenon as well as heat transfer coefficient has been obtained through the present simulation.
