Analytical solution of the equations of motion of a spherical particle suspended in a turbulent
flow near a plane wall has been obtained. The equations include the lift force and wall
effects on the drag force. The solution shows that the particle turbulent motion is affected by
the wall presence in the following manner:(a) The wall augments the response of the particle
to fluid turbulence. The ratio between the particle rms velocity fluctuation near the wall and
that of an identical particle in an unbounded flow is always greater than unity. This ratio …
