Observed coupling between air mass history, secondary growth of nucleation mode particles and aerosol pollution levels in Beijing [PDF]

, 2022
Atmospheric aerosols have significant effects on the climate and on human health. New particle formation (NPF) is globally an important source of aerosols but its relevance especially towards aerosol mass loadings in highly polluted regions is still ...

Fresh air in the 21st century? [PDF]

, 2003
Ozone is an air quality problem today for much of the world's population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the clean-air baseline levels of ...

Numerical Investigation of the Effect of Air Leaking into the Working Fluid on the Performance of a Steam Ejector

Applied Sciences, 2021
This paper investigated the effect of air leaking into the working fluid on the performance of a steam ejector. A simulation of the mixing of air into the primary and secondary fluids was performed using CFD. The effects of air with a 0, 0.1, 0.3 and 0.5
