Abstract

In this study, it is
aimed the numerically investigation of the flow of liner PTT
(Phan-Thien-Tanner) fluid, which is a viscoelastic fluid model over limited
square obstacle by finite volume method. The finite volume method has been used
for simultaneous solution of continuity, momentum and fluid model equations
with appropriate boundary conditions. The effects of the inertia  in terms of Reynolds number, Re, (0 < Re < 20) and the of elasticity 
in terms of Weissenberg number, We,
(1 < We < 15) of PTT flow  on vertical and shear stress areas are
examined in detail.

Keywords
