Foil 35 Euler's Equations Should Hold far from the Vehicle in Large Reynolds Number R Limit

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox

When R is large (small m) and quantities vary slowly (far from "aircraft"), then we can use Euler equations which put m=0 in Navier-Stokes equation.

Even these equations are nontrival and can be either be elliptic or parabolic

Euler's equations can lead to potential flow because
