Coriolis forces influence the secondary circulation of gravity currents flowing in large-scale sinuous submarine channel systems

Effect of the Earth’s Coriolis force on the large-scale circulation of turbulent Rayleigh-Bénard convection

We present measurements of the large-scale circulation LSC of turbulent Rayleigh-Bénard convection in water-filled cylindrical samples of heights equal to their diameters. The orientation of the LSC had an irregular time dependence, but revealed a net azimuthal rotation with an average period of about 3 days for Rayleigh numbers R 1010. On average there was also a tendency for the LSC to be ali...

On the Relation Between the Large-Scale Tropospheric Circulation and Air Quality in Tehran

The large-scale tropospheric circulation can play a controlling role in the accumulation and ventilation of air pollutants. It thus impacts air quality in large urban areas. This paper investigates the statistical relations between the dynamical indices related to circulation in the troposphere and visibility as a surrogate for air pollution in the urban area of Tehran for the climatological pe...

an investigation of the influence of longitudinal channel slope on secondary currents in compound channels using 2 d momentum model

secondary flow investigation could be regarded as an important issue in open channel flow, in spite of its lower quantity compared to the base flow in the water course. it should be given special consideration because of the influence on some hydraulic factors in open channel, specifically in compound channels. in compound channels' due to the difference in the flow velocity of the main ch...
