Abstract: Investigating urban wind and thermal environments is of great significance for the sustainable development of urban, residents' health, and urban suitability addressing climate change. With the continuous advancement of high-performance computational capacity and improvement of numerical methodologies, Computational Fluid Dynamics (CFD) has been widely utilized to numerically simulate urban wind and thermal environments. This study aims to summarize the research processes of CFD simulations in China on urban wind and thermal environments in the past two decades, including the typical experimental research methods, CFD numerical models, and model validation techniques as well as key findings, specifically addressing the impacts of architectural geometry and configuration, vegetation, water bodies, and cool materials. Finally, this study concludes by providing prospects for the future CFD simulation of urban wind and thermal environments, focusing on multiple seasons, multi-scale analysis, high-resolution simulation, and the coupling of various influencing factors, providing reference for future researches.
