Development of LES Methodology for the Analysis of High-Reynolds Number 2-D and 3-D Dynamic Stall Phenomenon

Abstract

The major objective of the AASERT Grant was to improve the analysis tools as well as assure the level of accuracy and efficiency that can be realized in the study of physics of the dynamic stall and related unsteady phenomena, through the development of the LES/DNS methodology. One M.S. and three Ph.D students were supported partially on this grant. The work carried out consisted of study of external unsteady flow using vorticity stream function formulation, analysis of boundary layer receptivity and transition using DNS methodology with spectral technique and, finally, compressibility effects in maneuvering body flows. Significant accomplishment is made in Object Oriented Numerics and high performance computing.
