Potential Flow Theory - MIT
web.mit.eduare called potential lines of the flow. In two dimensions ! d"= #" #x dx+ #" #y dy d"=udx+vdy Since ! d"=0 along a potential line, we have ! dy dx =" u v (4.4) Recall that streamlines are lines everywhere tangent to the velocity, ! dy dx = v u, so potential lines are perpendicular to the streamlines. For inviscid and irrotational flow is indeed
APPENDIX G HYDRAULIC GRADE LINE 1.0 Introduction 2
