    "abstract": "A three-dimensional direct numerical simulation (3D DNS) is performed to\ndescribe the turbulent flow in an enclosed rotor-stator cavity characterized by\na large aspect ratio $G=(b-a)/h=18.32$ and a small radius ratio $a/b=0.15$ ($a$\nand $b$ the inner and outer radii of the rotating disk and $h$ the interdisk\nspacing). Recent comparisons with velocity measurements have shown that, for\nthe rotational Reynolds number $Re=\\Omega b^2/\\nu=95000$ ($\\Omega$ the rate of\nrotation of the rotating disk and $\\nu$ the kinematic viscosity of water) under\nconsideration, the stator boundary layer is 3D turbulent and the rotor one is\nstill laminar. Budgets for the turbulence kinetic energy are here presented and\nhighlight some characteristic features of the effect of rotation on turbulence.\nA quadrant analysis of conditionally averaged velocities is also performed to\nidentify the contributions of different events (ejections and sweeps) on the\nReynolds shear stress.",
