Abstract
An analysis is made for a gas bubble impulsively started to rise with a con stant velocity in a quiescent liquid of infinite extent. Satisfactory resul ts for the total drag force are obtained for spherical air bubbles in water ; provided that the method developed here is applied at early times, the po w separation is negligible and the Reynolds number R-e is sufficiently larg e.
