Gross separation approaching a blunt trailing edge as the turbulence intensity increases.

A novel rational description of incompressible two-dimensional time-mean turbulent boundary layer (BL) flow separating from a bluff body at an arbitrarily large globally formed Reynolds number, Re, is devised. Partly in contrast to and partly complementing previous approaches, it predicts a pronounced delay of massive separation as the turbulence intensity level increases. This is bounded from ...

On the Euler Stage of Turbulent Separation near the Trailing Edge of a Bluff Body

A novel self-consistent description of time-mean two-dimensional turbulent-boundary-layer flow separating from a bluff body at arbitrarily large globally formed Reynolds numbers is presented. Contrasting with previous approaches, the theory deals with a sufficient delay of flow detachment or, correspondingly, increase of the turbulence intensity so as to both settle the question of the actual p...

After the Implosion: Trailing-Edge Guidelines for a New Era

In the Fall of 1989, I sat at a worn wooden desk with gum stuck to the bottom, listening to Professor Daniel Freed talk about the federal sentencing guidelines. I was captivated. Here, it seemed, there was a system of sentencing which demanded fairness, regularized punishment, and created a normative value for various wrongs. Professor Freed and virtually every other person in the room were str...

Flow visualization over a thick blunt trailing-edge airfoil with base cavity at low Reynolds numbers using PIV technique

ABSTRACT In this study, the effect of cutting the end of a thick airfoil and adding a cavity on its flow pattern is studied experimentally using PIV technique. First, by cutting 30% chord length of the Riso airfoil, a thick blunt trialing-edge airfoil is generated. The velocity field around the original airfoil and the new airfoil is measured by PIV technique and compared with each other. Then,...

Airfoil Leading and Trailing Edge Separation Control Using SDBD Plasma Actuators

Wind tunnel experiments were conducted to understand boundary layer separation control on airfoils. The objective of this research was to better implement flow control strategies with single dielectric barrier discharge (SDBD) plasma actuator designs for airfoils that exhibit both leading and trailing edge stall characteristics at realistic flight speeds and Reynolds numbers. The NASA energy ef...
