【 摘 要 】

In this study, a 3-D numerical model of a 400c.c four-stroke single-cylinder, water-cooledscooter engine is established and evaluated through computational fluid dynamics (CFD) with a conjugated heat transfer scheme to show the temperature distribution of the engine. The flow field of the water jacket is also observed, and the correlation between the heat transfer performance and flow field is discussed. In order to observe the real coolant flowing through the inside of the water jacket and make a comparison with the numerical results, we establish a transparent water jacket model using a 3-D printer. For the sake of developing the water jacket guidelines, we arrange the number of the gasket holes to acquire different flow fields and thermal results.
