The effects of the dissolved air concentration and atmospheric pressure on the motion of a rigid sphere along a wall in a fluid are studied experimentally. These effects are the result of the occurrence of a gas bubble in the lubrication layer betwee

A novel hydrodynamic effect, namely, slow contactless motion of a heavy spherical particle along an inclined wall, accompanied by the formation of a finite particle–wall clearance under the action of a cavitation-induced lift force, is investigated

In the slow motion of a spherical particle along a wall, a cavity in the form of a non-spherical bubble is detected visually in the narrow particle-wall clearance. The nondimensional parameters associated with cavity formation are formulated and the

At small Reynolds numbers, the gravity-driven motion of a solid spherical particle along an inclined plane in a Newtonian liquid initially at rest was studied experimentally. A comparison of the experiment with the calculations showed that motions bo
