The 'directional' source  A new type of singularity in potential flow
Abstract
A new class of two and threedimensional flowfields is examined. These solutions of Laplace's equation describe sources and sinks in which the source mass flux is allowed to vary with direction. A generalization of the classical simple source, emitting mass equally in all directions, is thus obtained. The flowfields resulting from such sources, as well as doublets and the effects of immersing these singularities in a uniform oncoming flow are described. Two cases of engineering interest, that of a curved Rankine body and a finned cylinder, are obtained by use of a directional source and doublet, respectively.
