On Master-Length Scale Formulations for Stable Conditions in Turbulence Closure Models
Paola Porretta-Tomaszewska, Lech Łobocki
Three formulations of the turbulence-length scales used in numerical modelling of atmospheric flows are compared. The comparison is made using the Mellor Yamada–Nakanishi–Niino turbulence closure model within the stable boundary layer local similarity framework. With an appropriate choice of model constants, the model predictions are barely discernible and compare well with the empirical data obtained from the SHEBA campaign.
