In a recent paper a generalized potential flow theory and its application to the solution of the Navier–Stokes equation are developed. 1 The purpose of this comment is to show that the analysis presented in that paper is in general not correct. We note that the theoretical development of Reference 1 is in fact an extension—although not cited—of some work first done by Hawthorne for steady inviscid flow. 2 Hawthorne's solution is correct, and his analysis, which we briefly describe, provides a useful introduction to this note.
