Abstract Ventilation and air circulation are essential elements in healthcare facilities. Moreover, good ventilation helps to dilute odour pollutants control the spread of disease. This generally uses mechanical ventilation, whereas use natural is encouraged by Indonesian Ministry Health World Organization due its affordability sustainability considerations. Therefore, this paper aims study opt...

The structure of the wind-driven circulation in the subtropical South Pacific is studied using simple diagnostic and analytical models. The diagnostic calculation is based on the Levitus climatology. The analytical model is forced by observed winter mixed layer density and depth calculated from the Levitus climatology and by the surface wind stress data from the Hellerman and Rosenstein climato...

Natural ventilation is a common way of for urban residents, which simple and energy-efficient. However, this not only introduces fresh air from outdoors into the indoor environment but also brings various pollutants environment, thus reducing quality causing series human respiratory diseases in severe cases, such as asthma, pneumonia, bronchitis, etc. In high-density proximity rooms within buil...

[1] High‐resolution numerical simulations of the northern Gulf of Mexico region using the Hybrid Coordinate Ocean Model (HYCOM) were employed to investigate the dynamical processes controlling the fate of the Mississippi River plume, in particular the conditions that favor cross‐marginal transport. The study focuses on the effects of topography, wind‐driven and eddy‐driven circulation on the of...

Urban ventilation plays an important role in regulating city climate and air quality. A numerical study was conducted to explore the ventilation effectiveness on the microclimate and pollutant removal in the urban street canyon based on the rebuilt Southern New Town region in Nanjing, China. The RNG k− ε turbulence model in the computational fluid dynamics (CFD) was employed to study the street...
