Upscaling of land-surface parameters through direct moment propagation [PDF]
Advances in Geosciences, 2005 A new methodology is presented that allows the upscaling of land surface parameters of a Soil-Vegetation-Atmosphere-Transfer (SVAT) Model. Focus is set on the proper representation of latent and sensible heat fluxes on grid scale at underlying subgrid ...

Large eddy simulation of aircraft at affordable cost: a milestone in computational fluid dynamics
Flow, 2021 While there have been numerous applications of large eddy simulations (LES) to complex flows, their application to practical engineering configurations, such as full aircraft models, have been limited to date.

Towards a Framework for the Stochastic Modelling of Subgrid Scale Fluxes for Large Eddy Simulation
Meteorologische Zeitschrift, 2015 We focus on a mixed deterministic-stochastic subgrid scale modelling strategy currently under development for application in Finite Volume Large Eddy Simulation (LES) codes.

Subgrid scale modelling for MILD combustion
Proceedings of the Combustion Institute, 2015 AbstractA simple closure for filtered reaction of a reaction progress variable is analysed in this study using explicitly filtered DNS data of turbulent MILD combustion of methane for Large Eddy Simulation (LES). The conditional averages of major and minor species mass fractions, and reaction rate constructed from the DNS data along with those obtained

Land surface modelling in hydrology and meteorology – lessons learned from the Baltic Basin [PDF]
Hydrology and Earth System Sciences, 2000 By both tradition and purpose, the land parameterization schemes of hydrological and meteorological models differ greatly. Meteorologists are concerned primarily with solving the energy balance, whereas hydrologists are most interested in the water ...

weather@home 2: validation of an improved global–regional climate modelling system [PDF]
Geoscientific Model Development, 2017 Extreme weather events can have large impacts on society and, in many regions, are expected to change in frequency and intensity with climate change. Owing to the relatively short observational record, climate models are useful tools as they allow for ...

International Journal for Numerical Methods in Fluids, EarlyView.This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

Atmosphere, 2019 Air pollution is probably the single largest environment risk to health and urban streets are the localized, relevant hotspots. Numerous studies reviewed the state-of-the-art models, proposed best-practice guidelines and explored, using various software,
