Large Eddy Simulation of the flow over a maneuvering 6:1 prolate spheroid

We study the flow around a 6:1 prolate spheroid under two maneuvers - pitch-up and streamwise acceleration. A kinetic energy conserving Large Eddy Simulation (LES) method is used to ensure precise simulation of small-scale turbulence and unsteady modes. Overset grid capabilities are employed to facilitate six degrees of freedom motion to simulate maneuvers. The goal is to develop an understanding of the vortex dynamics and interactions resulting from the 3D cross-flow separation, surface pressure and loading behavior of the spheroid. The work will also explore Reynolds number dependency and effect of maneuver specific parameters such as pitch-up rate and acceleration.
