Experimental Study of PVTx Properties of Mixture Refrigerant R1234yf/R134a
Zhileng xuebao, 2016 In order to get the thermophysical properties of mixed refrigerants R1234yf/R134a, the PVT properties of mixture refrigerant R1234yf/R134a with mass fraction 55%/45%, 50%/50%,45%/55% in the range of 268 ~ 323 K were measured by using high-precision PVTx ...

ISM equation of state and PVTx profile of polymer solutions
Physics and Chemistry of Liquids, 2018 An analytical equation of state (EoS) has been previously employed to predict the volumetric profile of several molten polymers. The appearing temperature-dependent parameters in the EoS were determined using corresponding states correlations based on ...

Pediatric liver transplantation from neonatal donors. [PDF]
Transpl Int, 1992 Sixteen recipients of neonatal liver grafts were compared with 114 contemporaneous pediatric recipients of grafts from older donors. Graft and patient survival were worse in the neonatal group although the differences were not statistically significant ...

Progresses in Fluid Inclusion Synthesis in Quartz
Geofluids, Volume 2022, Issue 1, 2022., 2022 High‐temperature and high‐pressure (HTHP) fluids are one of the most extensive participants in geological events. The representative in situ sampling of the HTHP fluids, which is an essential prerequisite for precisely characterizing the HTHP fluids (including compositional and volumetric properties), has been a vital challenge.

Geofluids, Volume 2021, Issue 1, 2021., 2021 A novel density model for computing quartz solubility in H2O‐CO2‐NaCl hydrothermal fluids applicable to wide ranges of temperature and pressure is proposed. Based on the models of Akinfiev and Diamond (2009) and Wei et al. (2012), the effective partial molar volume of water (VH2O∗) is replaced by the partial molar volume of water (V¯H2O) by ...

Isochoric PVTx Measurements for the Carbon Dioxide + 1,1-Difluoroethane Binary System [PDF]
Journal of Chemical & Engineering Data, 2007 PVTx measurements for carbon dioxide (CO2, R744) + 1,1-difluoroethane (CH3CHF2, R152a) for both the two-phase and the superheated vapor regions are presented. The measurements were taken with a constant volume apparatus at temperatures ranging from (223 to 343) K and pressures from (60 to 3890) kPa along eight isochores.

Analysis of PVTx measurements for binary mixtures of R115 and R114 [PDF]
International Journal of Thermophysics, 1990 We have made PVTξ measurements of R115 and R114 at temperatures from 296 to 443 K, pressures from 0.4 to 9.8 MPa, and densities from 153 to 1387 kg·m−3, for four compositions, namely, 25, 50, 75, and 100 wt% R115. The data were obtained along isochores.
