Thermal Balance Analysis of a Micro-Thermoelectric Gas Sensor Using Catalytic Combustion of Hydrogen

A thermoelectric gas sensor (TGS) with a combustion catalyst is a calorimetric sensor that changes the small heat of catalytic combustion into a signal voltage. We analyzed the thermal balance of a TGS to quantitatively estimate the sensor parameters. The voltage signal of a TGS was simulated, and the heat balance was calculated at two sections across the thermoelectric film of a TGS. The therm...

Development of a micro gas chromatograph for the analysis of hydrogen isotope gas mixtures in the fusion fuel cycle

Analysis of hydrogen isotopes is very important in the fuel cycle system of fusion reactors. Gas chromatography with a cryogenic separation column is one of the most extensively used methods for the analysis of hydrogen isotopes. Micro gas chromatograph (micro GC) with a cryogenic column is expected to improve the analysis time, that is a major disadvantage of conventional GC. The present autho...

Gas Chromatography for Combustion Gas Analysis

A basic discussion of the principles of gas chromatography and a description of a combustion gas analyzer using this chemical analysis techniqlJe are presented. During the past several years the combustion gas analyzer has been used extensively in airbreathing propulsion research projects at the APL Propulsion Research Laboratory to analyze samples from supersonic combustion and fuel-air mixing...

Flow of Gas Mixtures through Micro Channel

To investigate flow of gas mixtures through micro channel in detail, the tangential momentum accommodation coefficients of each species for gaseous mixtures were determined by analyzing the Couette flow problem of a slightly rarefied gas between two walls. The molecular dynamics (MD) method for the interaction of gas molecule with the wall surface is combined with the DSMC method for the motion...
