文摘

Viscoelastic flow past a bluff body is simulated by using Penalization method. Drag of the cylinder in viscoelastic flow is studied in a very board range parameter space. Drag behavior of the cylinder depends mostly on Reynolds number and Weissenberg number. The effect of viscosity ratio of polymer is pronounced at low Reynolds number and Weissenberg number.
