Large scale flow around turbulent spots
Numerical simulations of a model of plane Couette flow focusing on its in-plane spatio-temporal properties are used to study the dynamics of turbulent spots. While the core of a spot is filled with small scale velocity fluctuations, a large scale flow extending far away and occupying the full gap between the driving plates is revealed upon filtering out small scales. It is characterized by stre...
متن کاملImpact of large scale flows on turbulent transport
The impact of large scale flows on turbulent transport in magnetized plasmas is explored by means of various kinetic models. Zonal flows are found to lead to a nonlinear upshift of turbulent transport in a 3D kinetic model for interchange turbulence. Such a transition is absent from fluid simulations, performed with the same numerical tool, which also predict a much larger transport. The discre...
متن کاملModelling air flows around buildings in urban environment
In urban areas, main air flows from prevailing winds are strongly modified, depending on constructions’ morphology and urban microclimate’s effects. The meteorological data on the wind speed are often available from outside city centres whereas this wind speed is tough to assess in the urban canopy layer. The meteorological models which are developed from regional level to urban canopy layer le...
متن کاملA New Model for Prediction of Heat Eddy Diffusivity in Pipe Expansion Turbulent Flows
A new model to calculate heat eddy diffusivity in separating and reattaching flows based on modification of constant Prt is proposed. This modification is made using an empirical correlation between maximum Nusselt number and entrance Reynolds number. The model includes both the simplicity of Prt=0.9 assumption and the accuracy of two-equation heat-transfer models. Furthermore, an appropriate l...
متن کاملOn Implicit Subgrid Scale Modeling for Turbulent Flows
Large Eddy Simulation (LES) is an effective intermediate approach between DNS and RANS, capable of simulating flow features which cannot be handled with RANS such as significant flow unsteadiness and strong vortex-acoustic couplings, and providing higher accuracy than RANS at reasonable cost but still typically an order of magnitude more expensive. Desirable modeling choices involve selecting a...
