Summary: This study presents computational fluid dynamics (CFD) results of airflow, temperature, and humidity patterns in an insect-proof screenhouse. The results showed significant differences in airflow in the upper region of the screenhouse, with large-scale rotating airflow formed in the center. The leeward section was found to be warmer and have a lower humidity ratio compared to the windward section.

Summary: Skygardens are a unique architectural intervention that enhance the values of a building. This study investigates the potential of using vegetative barriers or shelterbelts to attenuate high wind speeds and improve wind and thermal comfort in skygardens. The results show that the combination of vegetative and geometrical barriers provides the most optimal condition. Additionally, vegetation can also attenuate pollutants and improve air quality.

Summary: This paper discusses the correlation between spatial accessibility and climate comfort by analyzing the spatial accessibility and CFD numerical simulation comfort of typical traditional villages in the Taihu Lake Basin. The study finds that the overall accessibility of Mingyuewan Village is poor and there is a weak correlation between wind environment and spatial accessibility. However, the thermal environment is strongly correlated with the degree of spatial accessibility. Therefore, it is suggested to consider the domination of seasonal wind by the lake surface, reserve windward outlets, and add green plants and shade facilities in green public open spaces.

Summary: Wind catchers serve as passive cooling systems to improve air quality, thermal comfort, and reduce energy consumption in the residential sector. This study numerically investigates the indoor flow structure and thermal comfort of a room integrated with a two-sided wind catcher, showing that lowering the room outlet elevation can increase the mass flow rate, and increasing the outlet area to wall ratio at a specific elevation can achieve desired temperature stratification and velocity field.

Summary: This study investigated the effect of wind speed and direction on the convective heat transfer coefficient of the human hand through computational fluid dynamics simulation, finding that different hand sections have varying local convective heat transfer coefficients due to specific geometry. The convective heat transfer coefficients of the fingers were higher than those of other hand sections, and increasing wind speed led to an overall increase in convective heat transfer coefficient of the hand, while wind direction had differing impacts on individual hand sections.

Summary: The paper reviews the evolution of computational wind engineering in terms of both environmental and structural perspectives since the inaugural conference of computational wind engineering held in Tokyo 30 years ago (CWE 92). The progress in computational methodologies and important aspects for accurate analysis are discussed, highlighting the importance of accurate modeling in atmospheric boundary layer, urban boundary layer, and urban canopy layer for the application of computational fluid dynamics (CFD) to various environmental issues. The paper also examines the most seminal contributions, showing that the engineering community has gained more benefits from environmental computational wind engineering applications. Future challenges in CFD applications and the need to bridge the gap between environmental and structural applications are thoroughly discussed.

Summary: This study evaluates the integrated effects of building height and upstream building on pedestrian comfort around lift-up buildings, showing that increasing building height, removing upstream buildings, and adjusting relative positions can improve wind comfort but the effects on thermal comfort vary seasonally. The findings provide inspiration for city planners to improve pedestrian comfort in high-density cities.

Summary: The present study investigates the effect of turbulent wind and shear wind on the structure of a floating offshore wind turbine using a high-fidelity computational fluid dynamics method. The study demonstrates that turbulent wind causes fluctuations in rotor thrust and power outputs, and results in faster wake diffusion compared to time-independent inflow wind. Wind shear exacerbates the decrease in local minimum thrust/power. However, under the current wind inflow conditions, neither turbulent wind nor wind shear significantly affect the inline surge force, dynamic motion, and mooring tension of the floater.

Summary: This study investigated wind-flow and wind-driven rain (WDR) patterns in 27 typical football stadium configurations in China using Computational Fluid Dynamics (CFD) simulations and wind tunnel testing. The results showed that the distribution of WDR on stands is significantly affected by cross-section types, stand arrangement, and roof geometry.

Summary: Sun and wind are important factors influencing outdoor thermal comfort. In this study, the impact of sun and wind on thermal sensation was compared, and it was found that sun had a greater influence than wind. The contributions of air temperature, sun, wind, and humidity to thermal sensation were 56%, 29.4%, 8.8%, and 5.9% respectively. The effect of sun was more than two times greater than that of wind.

Summary: The urban heat island (UHI) phenomenon and climate change are major concerns for city sustainability due to global warming and rapid urbanization. Water bodies are effective means to alleviate the UHI and improve urban microclimate's thermal environment. The study shows that water bodies can effectively improve thermal comfort conditions in isolated streets by reducing air and surface temperature, thus decreasing energy consumption, and increasing wind velocity during thermal stress peak times.
