RISA Shear-Based Parameterization of Turbulent Mixing in the Stable Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: n this study, shear-based parameterizations of turbulent mixing in the stable atmospheric boundary layer (SABL) are proposed. A relevant length-scale estimate for the mixing length of the turbulent momentum field is ...
Comparisons of Horizontal Axis Wind Turbine Wake Interaction Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, Reynoldsaveraged Navier–Stokes (RANS) simulations are performed using the kخµ and kد‰ shear stress transport (SST) turbulence closure schemes to investigate the interactions of horizontalaxis wind turbine ...
Biases in Thorpe-Scale Estimates of Turbulence Dissipation. Part I: Assessments from Large-Scale Overturns in Oceanographic Data
Publisher: American Meteorological Society
Abstract: ceanic density overturns are commonly used to parameterize the dissipation rate of turbulent kinetic energy. This method assumes a linear scaling between the Thorpe length scale LT and the Ozmidov length scale LO. Historic ...
