Abstract
The analysis and evaluation of the forces acting on
the particle in a linear shear flow of power-law fluid (PLF) in the presence of the wall were performed. Using the
results of a series of computations for a model problem with a spherical particle near a flat wall in the Reynolds number range of 0-200 and the distance to the wall from 0 to 20
particle diameters, the correlation formulas for calculating the coefficients
of drag force and lift force were obtained. Special attention was paid to the
behavior of the forces acting on the particle approaching the wall.
