Does Downscaling Improve the Performance of Urban Ozone Modeling?
Geophysical Research Letters, Volume 50, Issue 23, 16 December 2023., 2023 Abstract Increasing the model resolution is expected to be one way for improving air quality forecasts in urban areas. In this study, we evaluate the model performance in a large city at various resolutions to examine the best resolution for air pollution simulations.

Engineering Reports, Volume 5, Issue 3, March 2023., 2023 Large eddy simulation is used to simulate the process of flame acceleration and deflagration to detonation transition (DDT) of methane‐air mixtures in small scale 3D channel. This study reveals a principle feature of flame acceleration in channels with no‐slip walls, and the interaction between transverse waves, the pressure pulse and oblique shock ...

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 2, February 2023., 2023 Abstract We investigate the atmospheric diurnal variability inside and above the Amazonian rainforest for a representative day during the dry season. To this end, we combine high‐resolution large‐eddy simulations that are constrained and evaluated against a comprehensive observation set, including CO2 concentrations, gathered during GoAmazon2014/15. We

A time‐staggered second order conservative time scheme for variable density flow
International Journal for Numerical Methods in Fluids, Volume 94, Issue 12, Page 1964-1995, December 2022., 2022 Abstract In this study, we present a robust conservative time‐staggered scheme for variable density flow. This pressure correction scheme uses the compressible Navier–Stokes equations and is implemented in the collocated finite‐volume open‐source computational fluid dynamics solver code_saturne.

Wind Energy, Volume 25, Issue 11, Page 1917-1937, November 2022., 2022 Abstract Global dynamic response models used for the design of wind turbines are largely based on neutral stability, which is not representative of real atmospheric conditions. Offshore wind farms, for example, have been seen to experience predominantly unstable conditions, especially at lower wind speeds.

On stability and relaxation techniques for partitioned fluid‐structure interaction simulations
Engineering Reports, Volume 4, Issue 10, October 2022., 2022 This study contains a thorough investigation of the stability of partitioned FSI applied to turbulent flow with the hydrodynamic condition using a methodology recently published. This is a numerical benchmark for different relaxation providing useful insight in engineering applications in the design of a simulation. Abstract The stability of relaxation

Fluid–structure‐interaction simulations of forming‐air impact thermoforming
Polymer Engineering &Science, Volume 62, Issue 4, Page 1294-1309, April 2022., 2022 Flow pattern of annular nozzle during inflation. Abstract The authors present a thermally and dynamically coupled fluid–structure‐interaction (FSI) model of a thermoforming process variant along with simulation results. By purposeful arrangement of the inlet nozzles, the process variant under consideration seeks to improve the deformation behavior of a

Evaluating modelled winds over an urban area using ground‐based Doppler lidar observations
Meteorological Applications, Volume 29, Issue 2, March/April 2022., 2022 Long‐term weather model (MEPS) and analysis systems (LAPS) vertical wind verification against Doppler lidar observations in an urban environment showed variable strengths and weaknesses depending on the atmospheric conditions. Considerable horizontal biases were observed within the city domain. These further depend on the wind direction.

Journal of Advances in Modeling Earth Systems, Volume 14, Issue 3, March 2022., 2022 Abstract A segmentation algorithm is applied to high resolution simulations of shallow continental convection to identify individual convective 3D objects within the convective boundary layer, in order to investigate which properties of the objects vary with the object width.
