Roughing up wings—A promising technique in laminar flow control

Christmas Colloquium, London Taught Course Centre, December 2014

What role does the Reynolds’ stress play?

In 2006, Huebsch discovered the potential for dynamic roughnesses to suppress or delay separation on an airfoil.  Eight years and two papers later, optimism remains high that this may be a viable new technique for laminar flow control.  In this talk, I’ll aim to quickly navigate through the field of laminar flow control—highlighting the what, why and how—to show why the results in the papers to date (presented in the second half of this talk) are something worth getting excited about.
