Lohse}, title={Fluxes and energy dissipation in thermal convection and shear flows}, journal={EPL (Europhysics Letters)}, volume={78}, number={2}, pages={24001}, url={http://stacks.iop.org/0295-5075/78/i=2/a=24001}, year={2007}, abstract={We expose analogies between turbulence in a fluid heated from below (Rayleigh-Bénard (RB) flow) and shear flows: The unifying theory for RB flow (see Grossmann S. and Lohse D., J. Fluid Mech. , 407 (2000) 27 and subsequent refinements) can be extended to the flow between rotating cylinders (Taylor-Couette flow) and pipe (Poiseuille) flow. We identify "wind" dissipation rates and momentum fluxes that are analogous to the dissipation rate and heat flux in RB flow. The proposed unifying description for the three cases is consistent with the experimental data.} }
