Can Areawide Building Retrofitting Affect the Urban Microclimate? An LES Study for Berlin, Germany
Maronga, Bjørn; Winkler, Matthias; Li, Dan (Journal article; Peer reviewed, 2022)In this work, we investigate the effect of areawide building retrofitting on summertime, street-level outdoor temperatures in an urban district in Berlin, Germany. We perform two building-resolving, weeklong large-eddy ... -
The Departure from Mixed-Layer Similarity During the Afternoon Decay of Turbulence in the Free-Convective Boundary Layer: Results from Large-Eddy Simulations
Elguernaoui, Omar; Reuder, Joachim; Li, Dan; Maronga, Bjørn; Bakhoday Paskyabi, Mostafa; Wolf, Tobias; Esau, Igor (Journal article; Peer reviewed, 2023)This study analyses the departure of the velocity-variances profiles from their quasi-steady state described by the mixed-layer similarity, using large-eddy simulations with different prescribed shapes and time scales of ... -
An Investigation of the Grid Sensitivity in Large-Eddy Simulations of the Stable Boundary Layer
Maronga, Bjørn; Li, Dan (Journal article; Peer reviewed, 2021)We revisit the longstanding problem of grid sensitivity, i.e., the lack of grid convergence in large-eddy simulations (LES) of the stable boundary layer. We use a comprehensive set of LES of the well-known Global Energy ...
