✦ Synopsis
general two-dImensIonal lmear flow havmg pure shear (or two-dunenslonal extensional) flow as one hmlt and pure rotation as the other, with simple shear flow as an mtermedmte case IS discussed Calculations of the streamlmes around a ngd, neutrally buoyant sphere m creepmg flow mQcate that there are both closed and open streamlmes m the flow regunes between pure and simple shear, whereas only closed streamlmes exist between simple shear and pure rotation The only flow m which closed streamlines do not exist IS pure shear The trajectories of two neutral spheres of equal size m this family of flows have also been calculated Closed traJectorles do not exist In a large regune of flows near pure shear The slgmficance of these fmdmgs with pticular reference to hydrodynamic dlsperslon IS discussed
