The axisymmetric potential flow past a sphere almost touching a plane wall is solved in closed form and the solution used to show that the Virtual mass of the sphere is finite This result clears up a difficulty uncovered in calculations by Small and Weihs.

Abstract Using the method of successive images, an approximate solution for the velocity potential is obtained in closed form for incompressible flow about an ovary ellipsoid near a plane wall. The velocity distribution is computed from this solution in two ways. The first computation properly predicts differences in velocities on opposite half-meridians of the ellipsoid. A second method results in a symmetric velocity distribution but is useful for rapid estimates of the average wall effect. Pressure distributions calculated by this theory are compared with values measured on 4:1 and 6:1 ellipsoid models.
