A shrouded aerosol sampling inlet has been designed from high-speed aircraft. The sampling inlet was conducted using the CFD to perform a flow simulation. The shroud diameter is 150 mm. The inlet is located 180mm from the shroud entrance plane. The shroud is 300 mm long. Results are presented graphically, showing the shrouds have provided significant improvements in flow characteristics. Straighten the streamlines of gas of sampling inlet for flow angles up to five degrees. It is suggested that CFD simulation can be useful for improving the optimum a shrouded aerosol sampling inlet.
To assess some technologies which are more appropriate for the development of the iron and steel industry in China, a model was developed based on the Long range Energy Alternatives Planning System (LEAP) to assess the energy saving and CO2 reduction potentials from 2010 to 2040. The results show that the top three saving energy potentials is non-blast furnace iron-making accounted for 6.85%, device enlargement for 5.85%, advanced blast furnace for 4.84%, and also show that the top three CO2 reduction potentials is device enlargement accounted for 11.7%, non-blast furnace iron-making for 6.21%, advanced coke and blast furnace 5.52%. In the Mitigation scenario, it can reduce 28% of the initial energy demand and 35.2% of CO2 emissions. It can provide a method and data for search energy saving and CO2 reduction potentials in iron and steel industry by LEAP model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
