Abstract:We generalize an analogy between rotating and stratified shear flows. This analogy is summarized in Table 1. We use this analogy in the unstable case (centrifugally unstable flow vs. convection) to compute the torque in Taylor-Couette configuration, as a function of the Reynolds number. At low Reynolds numbers, when most of the dissipation comes from the mean flow, we predict that the non-dimensional torque G = T/ν2L, where L is the cylinder length, scales with Reynolds number R and… 

High-Reynolds number Taylor-Couette turbulence.

Taylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the

Torque scaling in turbulent Taylor-Couette flow with co- and counterrotating cylinders.

The transport is most efficient for the counterrotating case along the diagonal in phase space with ω(o) ≈ -0.4ω(i) and the exponent 0.38 corresponds to the ultimate regime scaling for the analogous Rayleigh-Bénard system.

Highly Turbulent Taylor-Couette Flow

The research issues addressed in this mostly experimental thesis concern highly turbulent Taylor-Couette (TC) flow (Re>105, implying Ta>1011). We study it on a fundamental level to aid our

Turbulent states in plane Couette flow with rotation

Shearing and rotational forces in fluids can significantly alter the transport of momentum. A numerical investigation was undertaken to study the role of these forces using plane Couette flow subject
