Dynamic Stall Modeling in Unsteady Flow

Traditionally, modeling unsteady aerodynamics is done in a CFD program. While this produces good results, it is a very time consuming process. Low order models have been developed to achieve similar results that take much less time. A Lumped Vortex Element (LVE) model is used in conjunction with leading edge vortex and trailing edge separation theories to create an accurate and fast representation of dynamic unsteady aerodynamics. This program is being designed in Julia with the goal of creating a single executable file that can handle a user-defined range of motions and geometries.
