Thermal instability induced by solar radiation is the most common condition of urban atmosphere in daytime. Compared to researches under neutral conditions, only a few numerical works studied the unstable urban boundary layer and the effect of buoyan

Wake separation is crucial to aircraft landing safety and is an important factor in airport operational efficiency. The near-ground evolution characteristics of wake vortices form the foundation of the wake separation system design. In this study, we

Vegetation constitutes one of the fundamental types of land use on Earth. The presence of trees in urban areas can decrease local winds and exchange sensible and latent heat with the surrounding environments, thus exerting notable influences on the u

The convective heat transfer coefficient (CHTC) of building surfaces is an important parameter to evaluate building thermal performance, and it also affects the calculation of sensible heat in urban canopy models. In this paper, The CHTCs at differen

A coupling scheme is proposed for the simulation of microscale flow and dispersion in which both the mesoscale field and small-scale turbulence are specified at the boundary of a microscale model. The small-scale turbulence is obtained individually i

The evolutions of aircraft wake vortices near ground in stable atmospheric boundary layer are studied by Large Eddy Simulation (LES). The sensitivity of vortex evolution to the Monin-Obukhov (M-O) scale is studied for the first time. The results indi

A new vortex sheet model was proposed for simulating aircraft wake vortex evolution. Rather than beginning with a pair of counter-rotating cylindrical vortices as in the traditional models, a lift-drag method is used to initialize a vortex sheet so t

The sensitivity of turbulence-development to inflow turbulent statistics is investigated in microscale urban atmospheric environment flows. Large-eddy simulations (LESs) are carried out, in which the inflow error is brought in by transforming a fully

Turbulent flow over a vegetation canopy under neutral atmospheric conditions is investigated using large-eddy simulation. Each model tree, which consists of a sphere-shaped tree crown and a cylindrical trunk, is fully resolved. The resulting turbulen

Large eddy simulation is performed for the dispersion of a passive scalar in the turbulent boundary layer over an urban-like roughness surface under neutral and stable stratification. Square arrays of cubical obstacles are used to model the urban can
