Numerical Study To Assess Sulfur Hexafluoride as a Medium for Testing Multielement Airfoils

Experimental and Numerical Investigation of Airflow and Contaminant Transport in an Airliner Cabin Mockup

The study of airflow and contaminant transport in airliner cabins is very important for creating a comfortable and healthy environment. This paper shows the results of such a study by conducting experimental measurements and numerical simulations of airflow and contaminant transport in a section of half occupied, twin-aisle cabin mockup. The air velocity and air temperature were measured by ult...

Detecting Photoacoustic Signals of Sulfur Hexafluoride at Varying Microphone Positions

Photoacoustic spectroscopy was used to test the photoacoustic properties of sulfur hexafluoride, an optically thick and potent greenhouse gas. While exploring the photoacoustic effect of sulfur hexafluoride, the effects of the position of the microphone within a gas cell were determined. Using a 35 cm gas cell, microphones were positioned at 17.5 cm, the middle of the gas cell, 12.5 cm, 7.5 cm,...

Zeolites for the selective adsorption of sulfur hexafluoride.

Molecular simulations have been used to investigate at the molecular level the suitability of zeolites with different topology on the adsorption, diffusion and separation of a nitrogen-sulfur hexafluoride mixture containing the latter at low concentration. This mixture represents the best alternative for the sulfur hexafluoride in industry since it reduces the use of this powerful greenhouse ga...

Sulfur Hexafluoride as a Mine Ventilation Research Tool - Recent Field Applications

Study of Post - Arc Plasma Behavior in an AG Circuit Breaker

In the search to obtain a better understanding of switching arc phenomena in the current intemrption, our attention has been focused on the study of arc plasma behavior in the alternative current circuit breaker. In this paper a comparison between intemrption capability of sulfur hexafluoride (SF6) and nitrogen (Nz) ballast arcs are made and we present physical aspects and characteristics of ar...
