Gas chromatography is mainly composed of the following parts: Carrier gas in a high-pressure cylinder with attendant pressure regulators and flow meters Helium, N2, H, Argon are used as carrier gases. Helium is preferred for thermal conductivity detectors because of its high thermal conductivity rel...
In the simulation test device, a nitrogen cylinder is used to fill high-purity nitrogen into the oil pipe to manufacture natural gas, and water is set outside the casing to cram into the annulus to affect the annular protection fluid. Plugs are formed at both ends of the pipe string ...
Fig. 5. Comparison of (a) density, (b) temperature, and (c) velocity magnitude obtained by uniGasFoam (solid lines), dsmcFoam+ (colour flood) and hybridDCFoam (dashed lines), for the flow past a cylinder case. A detailed comparison of the cylinder surface normal stress, shear stress, ...
