Coherent structure of zonal flow and onset of turbulent transport
Excitation of the turbulence in the range of drift wave frequency and zonal flow in magnetized plasmas is analyzed. Nonlinear stabilization effect on zonal flow drive is introduced, and the steady state solution is obtained. The condition for the onset of turbulent transport is obtained and partition ratio of fluctuation energy into turbulence and zonal flows is derived. The turbulent transport...
متن کاملNumerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel
In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...
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 کاملTurbulent Bursts in Couette-Taylor Flow.
We present a physical explanation of turbulent bursts in the flow between concentric, rotating cylinders (Couette-Taylor flow), based on fully resolved direct numerical calculations. The bursts are a temporal oscillation between a spatially laminar flow and turbulence, discovered experimentally by Hamill et al. The onset of turbulence is shown to be due to a linear instability of the spiral flo...
متن کاملLow-speed streak instability in near wall turbulence with adverse pressure gradient
A direct numerical simulation of a turbulent channel flow with a lower curved wall is performed at Reynolds number Reτ ≈ 600. Low-speed streak structures are extracted from the turbulent flow field and base flows formed with conditional streaks averages, superimposing the mean streamwise velocity profile, are used for linear stability analyses. The instability in the presence of a strong pressu...
