Significance of the strain-dominated region around a vortex on induced aerodynamic loads

The ability of vortices to induce aerodynamic loads on proximal surfaces plays a significant role in wide variety flows. However, most studies vortex-induced effects primarily focus analyzing the influence rotation-dominated cores vortices. In this work, we show that not only are viscous flows surrounded by strain-dominated regions, but these regions dynamically important and can sometimes even dictate induced loads. We demonstrate for pitching airfoil, which exhibits dynamic stall generates several force-inducing Using data-driven force partitioning method, quantify as well vortex-associated strain our current understanding vortex-dominated phenomena, such stall, is incomplete without considering substantial effect associated with
