2017年12月1日 · Nowadays, especially simulations with Computational Fluid Dynamics (CFD) is frequently used to assess urban microclimate. CFD can resolve the transfer of heat and mass and their interaction with individual obstacles such as buildings.

2022年1月1日 · CFD is a common tool to model urban microclimate with high-resolution results for various spatial and temporal scales (Blocken, 2015; Holland et al., 2015). It has been widely used to study urban wind and thermal comfort, pollutant dispersion, wind-driven rain, and building energy performance (Moonen et al., 2012).

2023年9月1日 · This review outlines historical and recent research progress on the accuracy of computational fluid dynamics (CFD) simulations of urban aerodynamics and microclimates and clarifies future research directions and significant challenges for accuracy and reliability using CFD in this field.

City4CFD--City for CFD--is a tool that aims to automatically reconstruct high-detailed 3D city geometries tailored for microscale urban flow simulations. It can automatically create a terrain from a point cloud and imprint different surfaces (e.g. green areas, water, roads).

2023年11月13日 · The integration of CFD with mesoscale meteorological models and cutting-edge machine learning techniques empowers high-resolution, precise simulations of urban meteorology, establishing a robust scientific basis for sustainable urban development, the mitigation of air pollution, and emergency response planning for hazardous substances.

2020年8月19日 · In particular, it is focused on: 1) microscale modelling of urban meteorology and pollutant dispersion at street and neighborhood scales by means of computational fluid dynamics (CFD) models and 2) parametrization of city effects on atmosphere at mesoscale (city scale) by using CFD simulations.

2019年12月18日 · We introduce a routine to create a cylindrical mesh that expedites the simulation of arbitrary wind directions using OpenFOAM. Results computed with the cylindrical domain are validated against wind tunnel data. We report that the cylindrical method yields comparable results in terms of accuracy and convergence behaviour.

2021年10月2日 · We propose a CFD algorithm for real-time prediction of urban flow and dispersion based on large-eddy simulation (LES). To efficiently handle complex urban building geometry, we implement a modified immersed boundary method (IBM), which can be applied to bluff building boundary on a staggered grid.

2021年6月1日 · Despite the popularity of the micro/urban climate CFD modeling as a powerful approach to simulate convective exchanges in urban areas, yet its application faces three profound limitations, including (1) computational barriers, (2) data acquisition, and (3) over-simplifications of underlying physics.
