2333 高分子溶液のヘルショウ流れに対する弾性の影響(S42-6 複雑流体の流動現象(6),S42 複雑流体の流動現象)  [in Japanese] 2333 Effect of Elasticity on Hele-Shaw Flow of Polymer Solutions  [in Japanese]

Effect of elasticity on the potential flow pattern in a Hele-Shaw cell is investigated by using three polymer solutions. While the inertia effect of Newtonian fluid causes the streamline separate from the body at its rear side, the elasticity of polymer solutions generates recirculating bubble around the upstream stagnation point. Regions for the potential flow, the inertia-affected and the elasticity-affected patterns are presented on the Re-We plane.
