Viscous Flow Induced in a Half Space by Two Sources with Different Strengths on a Wall

抄録

Viscous flow induced in a half space by two sources with different strengths on a wall is studied theoretically using Stokes' approximation. It is assumed that the flow is two-dimensional and incompressible. The forms of the separating streamline which divides the fluid coming out of one source from that of other source are obtained. That streamline becomes a closed curve in the case of the flow according to the source and sink. The area of the space bounded by this closed curve is very important in connection with fluid mixing and ventilation. That area in case of a viscous flow is larger than that of a potential flow.
