An Experimental Study for simulation of Pneumatic Conveying. 2nd Report. Lift and Drag Applied on a sphere in High Reynolds Number Linear Shear Flows.
Year: 1991
Type: article
Abstract: Effects of the velocity gradient of linear shear flows at a high Reynolds number (Re, s=4000-35000) on lift and drag applied on a spherical particle are investigated by measuring surface pressure distribution, using a pendant method, and by comparing computed and photographed trajectories of a sphere falling in upward shear flows. It is made clear that lift is applied on a sphere from the higher velocity side to the lower velocity side, that it increases as the velocity gradient becomes greater, and that drag is hardly affected by the velocity gradient.
