Effects of canopy heterogeneity, seed abscission and inertia on wind‐driven dispersal kernels of tree seeds (2008, methodology): “is a Lagrangian time scale for the particle obtained by modifying the Lagrangian time scale for the air (Csanady 1963; Reynolds & Lo Iacono 2004; Weil et al . 2004 ) to include the effects of the particle’s inertia”
Mechanistic models of seed dispersal by wind (2011, background): “The Lagrangian track is then completed for the simulated particle, which and can also accommodate seed inertia (Reynolds 1999; Weil et al. 2004).”
Overview of the PALM model system 6.0 (2019, methodology): “The LPM is based on Weil et al. (2004) to separate the particle speed into a deterministic and a stochastic contribution, which corresponds to dividing the turbulent flow field into a resolved-scale and a SGS portion, respectively.”
The Parallelized Large-Eddy Simulation Model (PALM) version 4.0 for atmospheric and oceanic flows: model formulation, recent developments, and future perspectives (2015, methodology): “13.2.3 Here, Re p is the particle Reynolds number The relative water supersaturation S is computed from the LES values of θ and q v , tri-linearly interpolated to the particle’s position.”
Formulation of the Dutch Atmospheric Large-Eddy Simulation (DALES) and overview of its applications (2010, methodology): “The calculation ofu follows Weil et al.(2004), and was tailored for use in LES with TKE-closure.”
