Lift Force

McLaughlin (1993) included the effects of presence of the wall in his analysis of the lift force. The results for particles in a shear field but not too close to the wall were given in tabulated forms. Cherukat and McLaughlin(1994) analyzed the life force acting on spherical particles near a wall as shown in Figure 2. Accordingly
