Rare fluctuations and large-scale circulation cessations in turbulent convection.
In turbulent Rayleigh-Bénard convection, a large-scale circulation (LSC) develops in a nearly vertical plane and is maintained by rising and falling plumes detaching from the unstable thermal boundary layers. Rare but large fluctuations in the LSC amplitude can lead to extinction of the LSC (a cessation event), followed by the reemergence of another LSC with a different (random) azimuthal orien...
متن کاملA model of diffusion in a potential well for the dynamics of the large-scale circulation in turbulent Rayleigh–Bénard convection
Experimental measurements of properties of the large-scale circulation LSC in turbulent convection of a fluid heated from below in a cylindrical container of aspect ratio 1 are presented and used to test a model of diffusion in a potential well for the LSC. The model consists of a pair of stochastic ordinary differential equations motivated by the Navier–Stokes equations. The two coupled equati...
متن کاملComment on "Effect of boundary layers asymmetry on heat transfer efficiency in turbulent Rayleigh-Bénard convection at very high Rayleigh numbers".
In turbulent Rayleigh-Bénard convection (a fluid between two parallel horizontal plates and heated from below) a transition was predicted to occur [1,2] with increasing Rayleigh number Ra from a ‘‘classical’’ state with laminar boundary layers (BLs) to an ‘‘ultimate’’ state with turbulent BLs. Recently, this transition was found in measurements of the Nusselt number Nu and Reynolds number Re as...
متن کاملTurbulent heat transport near critical points: Non-Boussinesq effects
Measurements of the Nusselt number N as a function of the Rayleigh number R using ethane gas near its critical point show that N is enhanced by non-Oberbeck-Boussinesq (NOB) effects when the top temperature approaches the coexistence curve. The empirical criterion that a small ∆ρ/ρ (ρ is the density) implies Boussinesq behavior is found not to be valid. An examination of data by Chavanne et al....
متن کاملInvestigation of the Effect of Nanoparticles Mean Diameter on Turbulent Mixed Convection of a Nanofluid in a Horizontal Curved tube Using a Two Phase Approach
Turbulent mixed convection of a nanofluid (water/Al2O3, Φ=.02) has been studied numerically. Two-phase mixture model has been used to investigate the effects of nanoparticles mean diameter on the flow parameters. Nanoparticles distribution at the tube cross section shows that the particles are uniformly dispersed. The non-uniformity of the particles distribution occurs in the case of large nano...
