Unstructured h-p Finite Elements for Unsteady High Speed Flows.
Abstract
There is currently a great interest in predicting the motion and corresponding loads of highly maneuverable aircraft capable of controlled flight at very high angles of attack. The design of air-to-air missiles could also benefit greatly from a better understanding of high angle of attack supersonic flight. Unsteady separation and formation of strongly asymmetric vortices from such bodies can introduce substantial lateral forces and yawing moments that must be counteracted or possibly used intelligently to aid in controlling the flight of the body. The majority of recent numerical studies has focused on steady and relatively low Mach number flows. Special algorithms have been developed for the design of high quality meshes to ensure convergence of the numerical solution in these complex configurations. The objective of this project is to develop hybrid DNS-LES numerical capabilities to predict forces and details of flow structure for unsteady viscous flows around complex geometry three dimensional aerodynamic configurations at high speed.
