10.1 NORMALIZED BOUNDARY LAYER EQUATIONS
Conservation equations have been derived for physical variables such as velocity
components, pressure, and temperature. However, a lot can be learned about the
solution of these equations if those variables are normalized. Consider the two-
dimensional, steady-state boundary layer equations [1]:
