Abstract

The motion of drops of liquid through an immiscible field liquid has been observed and drag coefficients have been measured at Reynolds numbers from 0.01 to 1500. Several kinds of motion have been distinguished and it has been noticed that a change in the motion is always preceded by an increase in the drag coefficient and is usually followed by a return to the drag coefficient for solid spheres. When the drop is deformed, the drag coefficient and the form of the motion is not determined solely by the Reynolds number. The effect of the walls of a containing vessel on the motion is computed for low Reynolds numbers.
