Quantifying transport into the lowermost stratosphere using simultaneous in-situ measurements of SF6 and CO2 [PDF]

open access: yes, 2008
The seasonality of transport and mixing of air into the lowermost stratosphere (LMS) is studied using distributions of mean age of air and a~mass balance approach, based on in-situ observations of SF6 and CO2 during the SPURT (Spurenstofftransport in der

Field Analysis of SF(6) Gas Insulated Cables and Its Application to Spacer Design [PDF]

open access: yes, 1974
This paper describes the spacer design for SF(6) gas insulated cables. The maximum electric stress within the cable is calculated by a numerical method, and it is recognized that the breakdown voltage depends linearly on the calculated values.

Compound-Specific δ^(34)S Analysis of Volatile Organics by Coupled GC/Multicollector-ICPMS [PDF]

open access: yes, 2009
We have developed a highly sensitive and robust method for the analysis of δ^(34)S in individual organic compounds by coupled gas chromatography (GC) and multicollector inductively coupled plasma mass spectrometry (MC-ICPMS).

Research progress on SF6 emission reduction methods and separation recovery

open access: yes工程科学学报
A potent greenhouse gas, SF6 has a global warming potential far exceeding that of CO2. Further, its stability in the atmosphere renders it a persistent threat to the climate.

Mechanism of Formation of SF6 Decomposition Gas Products and its Identification by GC-MS and Electrochemical methods: A mini Review

open access: yesInternational Journal of Electrochemical Science, 2015
The SF6 is commonly used as an insulating gas in different applications; however the SF6 can be easily exploded into different decomposition gas products when subjected to electrical discharge, such as electric arc, spark or corona.

Performance evaluation of ductless personalized ventilation in comparison with desk fans using numerical simulations [PDF]

open access: yes, 2020
The performance of ductless personalized ventilation (DPV) was compared to the performance of a typical desk fan since they are both stand-alone systems that allow the users to personalize their indoor environment.

Large-eddy simulation and multiscale modelling of a Richtmyer–Meshkov instability with reshock [PDF]

open access: yes, 2006
Large-eddy simulations of the Richtmyer–Meshkov instability with reshock are pre- sented and the results are compared with experiments. Several configurations of shocks initially travelling from light (air) to heavy (sulfur hexafluoride, SF6) have been ...

Atmospheric observation-based global SF6 emissions - comparison of top-down and bottom-up estimates [PDF]

open access: yes, 2009
Emissions of sulphur hexafluoride (SF6), one of the strongest greenhouse gases on a per molecule basis, are targeted to be collectively reduced under the Kyoto Protocol.
