About strength of a singularity

December 11, 2005, 04:42

What does it meant by strength of a singularity and how to compute it? Could you please explain in terms of mathematical terms?

The strength is the area/volume (2D/3D) integrated amplitude associated with the singularity. For example, the strength of a 2D vortex singularity is the circulation associated with that vortex. (use the definition of circulation as the area integral of vorticity, and substitute a delta function for the vorticity to see what I mean).
