متن کاملDYNAMIC SIMULATION OF A HIGH PRESSURE REGULATOR
In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

متن کاملHigh-pressure high-temperature synthesis and structure of α-tetragonal boron.
Microcrystals of α-tetragonal (α-t) boron with unit cell parameters a=9.05077(6) and c=5.13409(6) Å and measured density 2.16-2.22 g cm-3 were obtained by pyrolysis of decaborane B10H14 at pressures of 8-9 GPa and temperatures of 1100-1600 ○C. The crystal structure is in good agreement with the model proposed by Hoard et al (1958 J. Am. Chem. Soc.80 4507). However, compared to the original mode...
متن کاملFormation of As-As Interlayer Bonding in the collapsed tetragonal phase of NaFe2As2 under pressure
NaFe2As2 is investigated experimentally using powder x-ray diffraction and Raman spectroscopy at pressures up to 23 GPa at room temperature and using ab-initio calculations. The results reveal a pressure-induced structural modification at 4 GPa from the starting tetragonal to a collapsed tetragonal phase. We determined the changes in interatomic distances under pressure that allowed us to conne...
