PASC16 – Video on poster on Estimation of Drag and Lift Coefficients for Steady State Incompressible Flow

In this video from PASC16, Dimosthenis Pasadakis from Università della Svizzera italiana describes his poster: Estimation of Drag and Lift Coefficients for Steady State Incompressible Flow of a Newtonian Fluid on Domains with Periodic Roughness.

“Rough boundaries impose several challenges to fluid simulations. Their difficulty stems from the fact that resolving the small scale rough geometry requires significantly refined meshes in the vicinity of the boundaries. Since all physical rough boundaries have a characteristic length, scale corrections on the standard Navier-Stokes equations can be obtained by considering Taylor expansions around the rough surface, leading to modified boundary conditions. Numerical tests are presented to validate the proposed theory including the calculation of drag and lift coefficients for laminar flow around a cylinder with rough boundary”.

Thanks to Rich Brueckner from insideHPC Media Publications for recording the video.
