Creeping flow around a spherical bubble, when a liquid flows around a gas bubble, circulation takes place within the bubble. This circulation lowers the interfacial shear stress, and, to a first approximation, we may assume that it is entirely eliminated. Repeat the development of Ex. 4.2-1 for such a gas bubble, assuming it is spherical.
(a) Show that B.C. 2 of Ex. 4.2-1 is replaced by B.C.2; and that the problem set-up is otherwise the same.
(b) Obtain the following velocitycomponents:
