The rectangular simulation volume contains three bulk domains: a liquid domain in the middle with vapour on each side such that there are two vapour-liquid interfaces. The mass flux is generated by prescribing the chemical potential in control volumes in the vapour domains close to the outer ...
The latent heat requirements associated with this vapour formation must be provided by sensible heat conduction from the bulk liquid. We can write the energy balance at the interface as:(3)ρvhlvV˙sp=Aspq″, where ρv and hlv represent the vapour density and latent heat of evaporation, ...
8,9)). In addition, the derived mean molecular weight suggests an atmosphere still containing some hydrogen. The observations were recorded with the Hubble Space Telescope/Wide Field Camera 3 and analysed with our dedicated, publicly available, algorithms5,9. Although the suitability of M dwarfs ...
Here, we report a straightforward, vapour-phase-transport strategy for the transformation of IWW zeolite with low-density silica layers connected by labile Ge-rich units into material with new topology. In situ XRD and XANES studies on the mechanism of IWW rearrangement reveal an unusual structural...
aIt is the zone where weather phenomena and atmospheric turbulence are most marked. It contains 75% of the total molecular and gaseous mass of the atmosphere and virtually all the water vapour and aerosols. 它是区域,天气现象和大气动荡是最明显的。 它包含75%大气的总分子和气体大量和实际上所有水...
Moist air is fed to one side of an inherently water-permeable membrane, which has a low density of surface pores. While water vapor diffuses through the membrane preferentially, a small amount of air also leaks through the pores and carries the water vapor away from the membrane. In this ...
relation. Data also show that the resistance factor decreases with increasing mean relative humidity across the test specimen, with the wet-cup value consistently lower than the dry-cup values for a given material. The contribution of liquid film flow to mass transfer is discussed. It is shown ...
Isotopic composition of the surface oceanic water has been measured from daily taken samples since 30 June 2015, filled in narrow-mouth low-density polyethylene 20- or 30-mL plastic bottles, sealed with Parafilm M and stored at +4 °C from the end of the expedition until the measurement....
The initial assignment of UH+ molecular ions as from uranium hydride, which has the formal stoichiometry of UH3, is substantiated using existing time-of-flight (ToF) SIMS and density functional theory (DFT) evidence9. The DFT suggests that molecular UHx cations where x > 1 suffer from ...
