Massive separation on airfoils operating at high Reynolds number is an important problem to the aerodynamicist, since its onset generally determines the limiting performance of an airfoil, and it can lead to serious problems related to aircraft control as well as turbomachinery operation. The phenomenon of crossover between local separation and massive separation on realistic airfoil geometries induced by airfoil thickness is investigated for low speed (incompressible) flow. The problem is studied both for the asymptotic limit of infinite Reynolds number using triple-deck theory, and for finite Reynolds number using interacting boundary-layer theory. Numerical results are presented which follow the evolution of the flow as it develops from a mildly separated state to one dominated by the massively separated flow structure as the thickness of the airfoil geometry is systematically increased. The effect of turbulence upon the evolution of the flow is considered, and the impact is significant, with the principal effect being the suppression of the onset of separation. Finally, the effect of surface suction and injection for boundary-layer control is considered. The approach which was developed provides a valuable tool for the analysis of boundary-layer separation up to and beyond stall. Another important conclusion is that interacting boundary-layer theory provides an efficient tool for the analysis of the effect of turbulence and boundary-layer control upon separated vicsous flow.

1Man On The Other Side

By Ada Barnett

Ruth never expected to have a house of her own. Raised in an orphanage, she is forced to work for her living. She chooses to work in a book store, until the Great War. She serves in France and then marries. But what would she do with power? Would she be contented to settle down as a happy country wife? How would her husband take their very different backgrounds? - Summary by Stav Nisser

3Christmas Carol: The Miser's Warning

By Charles Zachary Barnett

This theatrical version of A Christmas Carol was performed at the Surrey Theatre in February 1844 just weeks after the publication of the novella by Dickens in December of the previous year. (There were 7 other adaptations also being shown on stage then, with only 1 version - not this one - being sanctioned by Dickens.) - Summary by ToddHW <BR><BR>Cast list:<BR> Ebenezer Scrooge, the Miser: <a href="https://librivox.org/reader/8011">Greg Giordano</a><br> Frank Freeheart, his Nephew: <a href="https://librivox.org/reader/18543">Agnes Robert Behr</a><br> Mr. Cheerly: <a href="https://librivox.org/reader/16205">James R.
