...Subrata K. Ghosh; R. K. Sahoo; Sunil K. Sarangi A study has been conducted to determine the off-design performance of cryogenic turboexpander. A theoretical model to predict the losses in the components of the turboexpander along the fluid flow path has been developed. The model uses a one...

... turbopump inducers, where the operating fluids are LH2 and LOx under cryogenic conditions. A ρ ( P , T ) state law modeling the cavitation phenomenon was integrated by the laboratory LEGI in the commercial computational fluid dynamics (CFD) code FINE/TURBO ™ , developed by Numeca International. Various 3D...

...Jonas P. R. Gustavsson; Kyle C. Denning; Corin Segal Cavitation was studied for a NACA0015 hydrofoil using a material that simulates cryogenic behavior. Several angles of attack and flow speeds up to 8.6 m ∕ s were tested. The material used, 2-trifluoromethyl-1,1,1,2,4,4,5,5,5-nonafluoro-3...

...Jie Liu; Walfre Franco; Guillermo Aguilar Cryogen spray cooling is an auxiliary procedure to dermatologic laser surgery, which consists of precooling the superficial skin layer (epidermis) during laser irradiation of subsurface targets to avoid nonspecific epidermal thermal damage. While previous...

... 27 04 2005 cryogenics mass transfer cooling refrigerators The pulse tube is among the simplest of all cryocoolers and has the advantage over the Stirling cryocooler of having no moving parts in the cold region, resulting in high reliability, long life, and low vibration...

...Jun Ishimoto, Associate Professor; Mamoru Oike, Associate Professor; Kenjiro Kamijo, Professor The two-dimensional characteristics of the vapor-liquid two-phase flow of liquid helium in a pipe are numerically investigated to realize the further development and high performance of new cryogenic...
