DNS of Herringbone Streaks in Rotating Turbulence Near Curved Walls

ORAL

Abstract

Near-wall streaks are a hallmark of turbulence. In turbulence near curved rotating walls the streaks form intricate herringbone-like patterns. We demonstrate the near-wall herringbone streaks using Taylor-Couette turbulence. We report the first direct numerical simulations of herringbone streaks in normal and counter-rotating Taylor-Couette turbulence, and characterize several of their remarkable aspects.
