Fpt. Baaijens et al., AN EXPERIMENTAL AND NUMERICAL INVESTIGATION OF A VISCOELASTIC FLOW AROUND A CYLINDER, Journal of rheology, 38(2), 1994, pp. 351-376
In this paper the plane flow of a shear thinning solution of 5 wt% pol
yisobutylene (PIB) in tetradecane (C14) (PIB/C14) around a cylinder pl
aced between parallel plates is investigated numerically and experimen
tally. Both Laser Doppler Anemometry and Flow Induced Birefringence me
asurements are performed and compared with numerical results, using a
Discontinuous Galerkin method and a one-mode Phan-Thien Tanner model.
Previous work has shown a good agreement between measured and computed
stress fields for the flow through a planar four-to-one contraction w
ith this fluid. The flow around a cylinder, however, leads to some sur
prising differences.
