Conjecture on the role of the turbulent length scale in the Prandtl–Kolmogorov model
Let $l(\boldsymbol{x},t)$ denote the turbulence length scale in the Prandtl–Kolmogorov $1$ -equation model, and let $k$ be its turbulent kinetic energy. The model also has a global…

Existence theory for the one-equation model with kinematic length scale
The one-equation turbulence model with kinematic length scale is the related model defined by equation (New1EqnModel) in the source. Existence-theory conjecture. An existence theor…

Conjecture on low-diffusion massfluxes causing turbulence-variable flux problems
The van Leer fluxes are observed to perform well in the computations. Low-diffusion massflux conjecture. Problems arise only when a low-diffusion (non-dissipative) massflux is used…
