Abstract:

This project addressed these gaps in the basic knowledge of dynamic stall through consistent, concise analysis of physics. The three primary objectives were: 1) extending the gains obtained thus far in numerical simulation of dynamic stall in two dimensions, including secondary vortex-shedding phenomena, 2) studying the nature of the physical phenomena that accompany dynamic stall in three dimensions, and 3) addressing the spatial and temporal numerical issues associated with modeling dynamic stall that are roadblocks in an engineering environment.
