Abstract

The paper considers the effect on the dusty gas otherwise at rest at infinity due to uniform motion of a sphere. The dust particles are assumed to have small relaxation time. Using the potential solution of gas flow at large Reynolds number R, an equation for the concentration of dust near the sphere is derived and solved numerically. It is also shown that particles do not collide with the sphere until the Stokes number is greater than 1/12 if we assume the gas flow unchanged by the presence of the dust particles and also graphically represented concentration of dust about sphere along radius vector.
