Journal ArticleDOI
The Parallelized Large-Eddy Simulation Model (PALM) version 4.0 for atmospheric and oceanic flows: model formulation, recent developments, and future perspectives
Björn Maronga,Micha Gryschka,Rieke Heinze,Fabian Hoffmann,Farah Kanani-Sühring,Marius Keck,Klaus Ketelsen,Marcus Oliver Letzel,Matthias Sühring,Siegfried Raasch +9 more
TL;DR: A detailed description of the current version of the Parallelized Large-Eddy Simulation Model (PALM) and its features, such as an embedded Lagrangian cloud model and the possibility to use Cartesian topography are given.
Journal ArticleDOI
High resolution urban large-eddy simulation studies from street canyon to neighbourhood scale
TL;DR: In this article, high-resolution urban large-eddy simulation (LES) studies are performed using the urban version of the parallelized LES model PALM, which is in line with experimental and previous LES results, i.e. superior to the faster/cheaper conventional Reynolds-averaged (RANS) models.
Journal ArticleDOI
LES Study of the Energy Imbalance Problem with Eddy Covariance Fluxes
TL;DR: In this article, the authors investigated the energy imbalance problem of single-tower measurements and the mechanism of the so-called energy imbalance through numerical experiments using large-eddy simulation (LES) for the daytime atmospheric boundary layer heated over a flat surface.
Journal ArticleDOI
Spatial representativeness of single tower measurements and the imbalance problem with eddy-covariance fluxes: results of a large-eddy simulation study
TL;DR: In this article, a large-eddy simulation (LES) study is presented that investigates the spatial variability of temporal eddy covariance fluxes and the systematic underestimation of representative fluxes linked to them.
Journal ArticleDOI
A Large-Eddy Simulation Study of Thermal Effects on Turbulent Flow and Dispersion in and above a Street Canyon
TL;DR: In this paper, the authors investigated thermal effects on turbulent flow and dispersion in and above an idealized street canyon with a street aspect ratio of 1 are numerically investigated using the parallelized large-eddy simulation model (PALM).
