Addendum (Helmholtz decomposition) to: “Potential flow of viscous fluids: Historical notes” [Int. J. Multiphase Flow 32 (2006) 285–310]

摘要

A framework for embedding the study of potential flow of viscous fluids, in which no special flow assumptions are made, is provided by Hemholtz decomposition, which says that every vector field u can be decomposed into a rotational part v and an irrotational part.
