Webow (the Main Deck), the perturbations are expressed as a perturbation of the stream lines trough a function A. We then presented the Blasius boundary layer, we emphasized the in … Triple-deck theory is a theory that describes a three-layered boundary-layer structure when sufficiently large disturbances are present in the boundary layer. This theory is able to successfully explain the phenomenon of boundary layer separation, but it has found applications in many other flow setups as well, including the scaling of the lower-branch instability (T-S) of the Blasius flow, boundary layers in swirling flows, etc. James Lighthill, Lev Landau and others were t…

Webthe present results with triple-deck solutions recently obtained by other investigators for the symmetric problem is presented. Also presented are some comparisons of the pres-ent solution with low Reynolds number (R s 200) solutions of the Navier-Stokes equations and with experimental data. These comparisons indicate that the asymptotic triple ... WebA triple- deck analysis of a supersonic flow involving a tempera- ture jump was chosen as a more tractable "pathfinder" before embarking on the more complex triple-deck analysis of a.nonequilibrium, catalytic jump problem. The derivation of this triple-deck analysis is originally presented in an earlier paper.'
