Inner-outer Interaction Predictive Model for Wall-bounded Turbulence Subjected to Pressure Gradient Effect
In an early work, Marusic, Mathis & Hutchins (2010) developed a model ables to reconstruct the streamwise turbulence fluctuation of the inner-layer in zero-pressuregradient, flat-plate, turbulent boundary layer. The originality of this model, which is based on scales interaction, is that it requires as input only one localised information (e.g. one measurement point) about large-scale log-regio...
متن کاملLarge-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer
Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
متن کاملAn extended view of the inner-outer interaction model for wall- bounded turbulence using spectral linear stochastic estimation
Streamwise velocity fluctuations in the inner-region of wall-bounded turbulent flows can be predicted by the model of Marusic, Mathis & Hutchins (2010). Only a single large-scale velocity signal from an outer position in the logarithmic region is needed for the model, and all other parameters are determined from a once-off calibration experiment. Here we elucidate part of the model by investiga...
متن کاملIsolating Curvature Effects in Computing Wall-Bounded Turbulent Flows
The ow over the zero-pressure-gradient So-Mellor convex curved wall is simulated using the NavierStokes equations. An inviscid e ective outer wall shape, undocumented in the experiment, is obtained by using an adjoint optimization method with the desired pressure distribution on the inner wall as the cost function. Using this wall shape with a NavierStokes method, the abilities of various turbu...
متن کاملDirect numerical simulation of turbulent channel flow up to Re τ ≈ 5200
A direct numerical simulation of incompressible channel flow at Reτ = 5186 has been performed, and the flow exhibits a number of the characteristics of high Reynolds number wall-bounded turbulent flows. For example, a region where the mean velocity has a logarithmic variation is observed, with von Kármán constant κ = 0.384 ± 0.004. There is also a logarithmic dependence of the variance of the s...
