Abstract

The two-dimensional (2D) steady, incompressible, Stokes flow is considered in a T-shaped cavitywhich has the upper-lid moving in horizontal directions. A Galerkin finite element method is used to investigatea new eddy generation and flow bifurcation. The flow in a cavity is controlled by two parameters 1 h and 2hwhich are associated with the heights of the T-shaped domain. By varying 1h and 2h , the second eddyformation mechanism and the 12, hh control space diagram are obtained.

Özet

Üst kapağı yatay yönde hareket eden T şeklindeki kaviti içerisindeki iki boyutlu (2D) durağan, sıkıştırılamaz, Stokes akış ele alındı. Yeni girdap oluşumunu ve akış çatallanmasını araştırmak için Galerkin sonlu elemanlar yöntemi kullanıldı. Kaviti içersindeki akış, T-şeklindeki bölgenin 1h ve 2h yükseklik parametreleri tarafından kotrol edilir. 1h ve 2h yüksekliklerinin değişmesiyle meydana gelen girdap oluşum mekanizması ve 1 2 , hh kontrol uzay diyagramı elde edildi.
