Roughing up wings: A promising technique in laminar flow control
Young Researchers in Mathematics, Oxford University, August 2015
Laminar flow control—the process of influencing the structure of a laminar boundary layer as it moves over a surface—is important in the field of aerodynamics for the purposes of drag reduction and safety: new and more effective techniques are constantly being sought. The work of Huebsch (2006), Huebsch & Rothmayer (2011) and Huebsch et al. (2012) demonstrates the potential of small dynamic roughnesses for delaying or suppressing the separation of a laminar boundary layer from a surface. In this talk, I’ll present their numerical and experimental results, as well as the conclusions from our 2D model.
