Drag enhancement with polymers

Francois, Nicolas; Lasne, D.; Amarouchene, Y.; Lounis, B.; Kellay, H.


Drag on a cylinder can be enhanced in the presence of polymers. This enhancement is directly related to the interaction of the polymers with the flow around the obstacle. The presence of the polymers modifies the flow in the vicinity of the cylinder giving rise to a band of higher shear, large molecular elongations and large velocity fluctuations. The measured drag on the cylinder is directly related to the modification of the flow field by the presence of the polymers.
