چکیده مقاله:

Shrinking the size ofengine has been a great interest for many years. Providing more a heat transfermay supply possibilities for size reduction in engine parts, specifically the engine water jacket that is ofinterest for the present study. Boiling phenomenon, by providing more heat transfer in comparisonwith single-phase, provides conditions for size reduction. In this paper, an experimental correlation hasbeen introduced in order to model boiling effect in a gasoline engine. In this work effects of boilinghave been considered through calculation of the coolant convection coefficient. The correlation and themethod have been used to simulate thermal behavior of the coolant within water jacket of a gasolineengine. Data show that the proposed model has good accuracy and it can be employed in designprocedure. Finally, the onset of boiling phenomenon as well as heat transfer coefficient has beenobtained through the present simulation.
