Reynolds Stress and Eddy Diffusivity of b-Plane Shear Flows

The Reynolds stress induced by anisotropically forcing an unbounded Couette flow, with uniform shear g, on a b plane, is calculated in conjunction with the eddy diffusivity of a coevolving passive tracer. The flow is damped by linear drag on a time scale m. The stochastic forcing is white noise in time and its spatial anisotropy is controlled by a parameter a that characterizes whether eddies a...

Verification of Reynolds stress parameterizations from simulations

Key words hydrodynamics – methods: numerical – turbulence We determine the timescales associated with turbulent decay and isotropization in closure models using anisotropically forced and freely decaying turbulence simulations and study the applicability of these models. We compare the results from anisotropically forced three-dimensional numerical simulations with the predictions of the closur...

Analysis of Herat embroidery patterns from the perspective of fractal geometry

Geometric shapes and motifs are a combination of the human spiritual mind which sees the existence of beautiful and paints a historical civilization through this vision. The geometric motifs are an expression of the rhythmic and balanced human beings possessions when the human being wants to imagine beyond the present and create a world full of love. The patterns/shapes are the basis of artwork...

Toward Large-eddy/reynolds-averaged Simulation of Supersonic Combustion

While flamelet-based progress variable models have matured to production-level in recent years for incompressible flows, little development toward compressible formulations of the flamelet model has ensued. For supersonic and hypersonic flows exhibiting combustion, an applicable flamelet-based combustion model must reflect the compressible nature of the flow, the tight coupling of the flow and ...

Spectral and hyper eddy viscosity in high-Reynolds-number turbulence

For the purpose of studying the spectral properties of energy transfer between large and small scales in high-Reynolds-number turbulence, we measure the longitudinal subgrid-scale (SGS) dissipation spectrum, defined as the co-spectrum of the SGS stress and filtered strain-rate tensors. An array of four closely spaced X-wire probes enables us to approximate a two-dimensional box filter by averag...
