Abstract

Behaviour of a steady laminar wake behind a cylindrical body 10cated in a uniform flow of dilute polymer solutions is analized with linear approximations. The results show that in case of strong viscoelastic behaviour of flow such as past a fine wire, a drag coefficient and a mean Nusselt number do not depend on the Reynolds number but depend on the ratio of elastic to inertial forces and that recovery of wake velocity occurs farther downstream than in case of Newtonian fluid flow.
