Abstract:
We present the Direct Numerical Simulations of high Reynolds numbers vortical flows employing vortex methods. The simulations involve a highly efficient implementation on massively parallel computers, enabling unprecedented simulations using billions of particles.
Present results of this work include the investigation of the implementation performance up to 16k IBM BG/L nodes and the study of multiple wavelength instabilities in aircraft wakes, enabling state of the art calculations at high Re numbers.
Ongoing developments include simulations using up to 32k processors, the implementation of unbounded conditions and the evolutionary optimization of flow decay and mixing.
