11/18/2010 2 Momentum Integral (9-4) Consider incompressible, steady, 2D flow over a solid surface We will use a differential CV in the BL and want to find δ(x) Note that the dashed line is δ(x) There is NO mass flux across ad. There is mass flux across ab and cd What about bc? 3 Momentum Integral (9-4) Apply continuity with assumption of steady, 2D flow to our differential CV Consider the mass flux across each face ab 4
