Summary

A solution for the early flow around an impulsively started sphere in a viscous fluid has been developed in powers of the time from the start of the motion. The boundary-layer solution considered by E. Boltze has been extended and solutions of this type have been developed to include the effect of finite Reynolds numbers. For high Reynolds numbers the time series is valid past the time when separation occurs and a number of characteristic flow properties can be calculated with reasonable accuracy.
