Abstract:	Experimental settling velocities for three different sizes of Delrin spheres in Ucon lubricant were determined at 20.2 degrees Celsius in order to confirm the validity of a theoretically derived equation for the settling of a sphere in the proximity of a corner. The experiments were conducted in a wedge shaped column with a circular sector base, filled with the viscous fluid, where the angle of the wedge was varied for experimental purposes. The distance from the wedge apex to the particle was also changed for the different runs. The experimental data gave a good approximation of the values evaluated by the basic equation utilizing the drag force considering the wedge walls only. A modified form of the basic equation considering the additional drag from the vessel wall showed an improved agreement with the experimental data.
