being introduced into the Pelton Wheel at the saturation temperature or at a temperature slightly above the saturation temperature of the liquefied gas; and raising the enthalpy of the liquefied gas after it has been withdrawn from the Pelton Wheel to an enthalpy above the enthalpy of saturated ...
Unsteady adiabatic isentropic expansion of gas into vacuum from a toroidal puff valve 来自 Semantic Scholar 喜欢 0 阅读量: 56 作者:PD Pedrow,AM Nasiruddin,R Mahalingam 摘要: Observations were made on the expansion of polyatomic (CF4) and diatomic (O2) gases into vacuum from a toroidal puff ...
Gas separated in the third separation (85) is cooled to produce a mixture of gas and liquid, which is phase separated (103 or 123). Gas from the latter phase separation is expanded isentropically in the second expansion engine (137), and refrigeration from material from second expansion ...
The tests data testify to = continuous change of metals properties at expansion from the condensed = state up to the gas state. Isentropes of explosion products (EP). In tests the shock wave = parameters were determined in inert materials-obstacles directly = contacting HE under research. TNT...

•Expansion energy of sudden hydrogen release from onboard storage vessel is calculated.•Ideal then real gas equations of state are used to describe the release.•Temperature is shown to better control burst energy than pressure.•Cryogenic storage can reduce burst energy by a factor of up...
The change of entropy for a perfect gas is given by ΔS12=s2−s1=cPlnT2T1−Rlnp2p1where, from the perfect gas law, R=(κ−1)cpκ=(1.35−1)×1.1001.35=0.285kJ/kg K Thus the change of entropy during the expansion process is s2−s1=1.1ln7861273−0.285ln110=−0.5304...
