Clipping over dissipation in turbulence models
Kiera Kean, William Layton, Michael Schneier
Clipping refers to adding 1 line of code A=min{A,B} to force the variable A to stay below a present bound B. Phenomenological clipping also occurs in turbulence models to correct f…

On the Prandtl-Kolmogorov 1-equation model of turbulence
Kiera Kean, William Layton, Michael Schneier
We prove an estimate of total (viscous plus modelled turbulent) energy dissipation in general eddy viscosity models for shear flows. For general eddy viscosity models, we show that…
