FIG. 3.

Parameters affecting the nondimensional inertial lift force. (a) The nondimensional force [f_L = F_L/(ρU_m²a⁴/H²)] is plotted as a function of the fractional distance from the channel center line for the controlling dimensionless parameters. (b) The dimensionless lift force is plotted using a new functional dependence on a/H that better collapses the data near the channel center line [f_L • (a/H)]. (c) Normalization of the lift is modified such that one can observe collapse to a single curve in the nearwall region. (d) The lift force in the near-wall region (x/h > 0.52) appears to decrease with increasing R_c, but f_L is seen to increase near the channel center line (x/h > 0.52) for R_c greater than 60.
