The flow of fluids is central to many important natural phenomena and engineering technologies, where turbulence often plays a dominant role. Turbulence is notoriously complex, and its effects are difficult to predict or manipulate, which limits our ability to develop novel technologies to address important problems. Yeung is using Blue Waters to conduct direct numerical simulations of three high Reynolds number turbulent flows: a turbulent non-premixed methane flame, scalar mixing and particle dispersion is isotropic turbulence, and turbulent wall-bounded flow in a channel. In each case, the focus is on reaching sufficiently high Reynolds number to explore the physics that arise in applications. The simulations will address fundamental research issues relevant to energy production (turbulent combustion) and consumption (transportation) technologies.
