Viscosity represents the most important property of turbulent flows, yet its impact of its variation on turbulence dynamics is not yet fully understood. This project addresses how the dissipation mechanism and self-similarity of turbulent flows are affected by fluctuations in viscosity—questions that can help lead to better turbulent mixing models, and, in turn, improved predictions of pollutants in combustion engines. Highly resolved direct numerical simulations of turbulent shear flows on JUQUEEN with up to 231 billion grid points were performed in pursuit of an answer to this question.
