..., in most cases, is a phenomenon that develops at a constant temperature, and only a relatively small amount of heat is required for the formation of a significant volume of vapor, and the flow is assumed isothermal. However, in some cases, such as thermosensible fluids and cryogenic liquid, the heat...

...Gang Xu; HongGuang Jin; YongPing Yang; Liqiang Duan; Wei Han; Lin Gao In this paper, we have proposed a novel coal-based hydrogen production system with low CO 2 emission. In this novel system, a pressure swing adsorption H 2 production process and a CO 2 cryogenic capture process are well...

...Lawrence Hawkins; Alexei Filatov; Shamim Imani; Darren Prosser A cryogenic gas expander system that incorporates a high-performance, high-speed permanent magnet, direct-drive generator and low loss magnetic bearings is described. Flow loop testing to 30,000 rpm was completed at the system...

... will be described, including the benefits and drawbacks of each. Cryogenic ASU technology will be summarized for both low-pressure and elevated-pressure applications and key design and integration issues will be identified and discussed. Finally, membrane-based ASU technology will be described and contrasted...

..., and the use of cryogenics as lubricants. The importance of using appropriate simulators that duplicate the actual equipment in evaluating the application of compliant bearings is demonstrated via two specific examples; one, a simulator to evaluate bearings for an air cycle machine and another for an advanced...

... at 23,600 rpm with cryogenic fluid (LH2) for a 0 to 100 percent of clearance-wear range. Their theoretical case and the present experimental case are not comparable due to completely different fluid characteristics. Specifically, their model does...
