Moore, D.W., 1965: The velocity of rise of distorted gas bubbles in a liquid of small viscosity. J. Fluid Mech., 23, no. 4, -766.

The terminal velocity of rise of small, distorted gas bubbles in a liquid of small viscosity is calculated. Small viscosity means that the dimensionless group gμ4/ρT3 where g is the acceleration of gravity, μ the viscosity, ρ the density and T the surface tension, is less than 10-8. It is assumed — and the numerical accuracy of the assumption is discussed — that the distorted bubbles are oblate ellipsoids of revolution. The drag coefficient is found by extending the theory given recently (Moore 1963) for the boundary layer on a spherical gas bubble. The results are in reasonable quantitative agreement with the experimental data.
