Two-dimensional isotropic turbulent inflow conditions for vortex particle method

Abstract: The unsteady loading on an airfoil due to the inflow turbulence is the primary source of broadband noise in turbomachinery, which makes the modeling of the inflow conditions a crucial task. This Rapid Communication presents an advanced method to model isotropic turbulent inflow conditions for a two-dimensional vortex particle method. The method relies on the classical view of turbulence as a superposition of random vortices convected with the mean flow. The fluctuating velocity is formulated using the scalar p… Show more

“…The turbulent velocity field reconstruction involves combining disturbances from discrete vortex particles, each influencing the overall field. Classical point vortices encounter singularity at close distances, leading to nonphysical behaviors [20]. Mollified vortices with finite cores address this [21].…”
