Abstract

In this study, FLUENT package program based on the finite volume method was used to model the flow in the cylinder of an internal combustion engine. Numerical studies were carried out at 5 and 7 mm valve clearances. The variation of velocity vectors, streamlines and vortex values was obtained along the cylinder. Besides this, the flow structure was determined to change with the valve clearance and along the cylinder stroke.

Özet

Bu çalısmada, silindir içi akıslar bir silindir-supap modelinde 5 ve 7 mm supap açıklıklarında sonlu hacimler yöntemi (FLUENT paket programı) kullanılarak incelenmistir. Silindir içerisinde olusan akısın hız vektörleri, akım çizgileri ve girdap değerlerinin değisimi elde edilmis olup, akıs yapısının supap açıklığı ile silindir kafasından olan mesafeye bağlı olarak değisimi belirlenmistir.
