Stochastic modelling of the instantaneous velocity profile in rough-wall turbulent boundary layers
Roozbeh Ehsani, Michael Heisel, Jiaqi Li +3
The statistical properties of Uniform Momentum Zones (UMZs) are extracted from laboratory and field measurements in rough wall turbulent boundary layers to formulate a set of stoch…
On the departure from Monin-Obukhov surface similarity and transition to the convective mixed layer
Michael Heisel, Marcelo Chamecki
Large-eddy simulations are used to evaluate mean profile similarity in the convective boundary layer (CBL). Particular care is taken regarding the grid sensitivity of the profiles…
Evidence of mixed scaling for mean profile similarity in the stable atmospheric surface layer
Michael Heisel, Marcelo Chamecki
A new mixed scaling parameter is proposed for similarity in the stable atmospheric surface layer, where is the height, is the Obukhov length, and is the…
Turbulence organization and mean profile shapes in the stably stratified boundary layer: zones of uniform momentum and air temperature
Michael Heisel, Peter P Sullivan, Gabriel G Katul +1
A persistent spatial organization of eddies is identified in the lowest portion of the stably-stratified planetary boundary layer. The analysis uses flow realizations from publishe…
Self-similar geometries within the inertial subrange of scales in boundary layer turbulence
Michael Heisel, Charitha M. de Silva, Gabriel G. Katul +1
The inertial subrange of turbulent scales is commonly reflected by a power law signature in ensemble statistics such as the energy spectrum and structure functions - both in theory…
Effect of finite Reynolds number on self-similar crossing statistics and fractal measurements in turbulence
Michael Heisel
Stochastic simulations are used to create synthetic one-dimensional telegraph approximation (TA) signals based on turbulent zero crossings, where the interval between crossings is…
Settling and Clustering of Snow Particles in Atmospheric Turbulence
Cheng Li, Kaeul Lim, Tim Berk +5
The effect of turbulence on snow precipitation is not incorporated into present weather forecasting models. Here we show evidence that turbulence is in fact a key influence on both…
On the mixing length eddies and logarithmic mean velocity profile in wall turbulence
Michael Heisel, Charitha M. de Silva, Nicholas Hutchins +2
Since the introduction of the logarithmic law of the wall more than 80 years ago, the equation for the mean velocity profile in turbulent boundary layers has been widely applied to…
