WebThe above relation derived from Blasius boundary layer, ... The above equation, which is derived from Prandtl's one-seventh-power law, provided a reasonable approximation of the drag coefficient of low-Reynolds-number turbulent boundary layers. Compared to laminar flows, the skin friction coefficient of turbulent flows lowers more slowly as the ... WebSep 28, 2016 · We consider a Prandtl model derived from MHD in the Prandtl-Hartmann regime that has a damping term due to the effect of the Hartmann boundary layer. ... A new class of data is found for which the Prandtl boundary layer equations and the hydrostatic Euler equations are locally in time well-posed and the local existence and uniqueness …
