Limits on the transport of heat and momentum by turbulent convection with large-scale flow. (English) Zbl 0707.76052
Summary: Under certain conditions, high-Rayleigh-number convection in a horizontal layer exhibits an organized pattern of large-scale flow superposed on an irregular structure of turbulent plumes. Bounds on the heat and momentum fluxes in such a flow, which provide upper estimates of the possible level of the large-scale flow, are presented.
