Evolution of Supersonic Modes in Hypersonic High-Enthalpy Boundary Layer Transition
气体物理, 2023 With continuous expansion of flight speed and altitude domains, the high-temperature gas effects, especially the thermochemical non-equilibrium (TCNE) effects in hypersonic high-enthalpy boundary layers invalidated the calorically perfect gas (CPG ...

Direct Images of the Virtual Source in a Supersonic Expansion
The Journal of Physical Chemistry A, 2007 Direct images of the virtual source in a supersonic expansion of helium are presented. The images were obtained using a Fresnel zone plate with free-standing zones, 540 microm in diameter and with an outermost zone width of 50 nm. The general method can be extended to other beams, including seeded beams. Measurements were carried out at absolute source

Properties of water and argon clusters developed in supersonic expansions
The Journal of Chemical Physics, 2023 Using adiabatic molecular dynamics coupled with the fluid dynamics equations, we model nucleation in an expanding beam of water vapor and argon on a microsecond scale. The size distribution of clusters, their temperature, and pickup cross sections in dependence on velocity are investigated and compared to the geometric cross sections and the experiment.

Theoretical Study of a Novel CO2 Supersonic Two-phase Expansion Refrigeration Cycle
Zhileng xuebao, 2021 Natural refrigerants such as CO2 have become a research hotspot. Under high-pressure conditions, a large throttling loss becomes the primary reason for the low circulation efficiency of the CO2 refrigeration cycle. Therefore, reducing the throttling loss
