Electric Dipole Moments from Stark Effect in Supersonic Expansion: n-Propanol, n-Butanol, and n-Butyl Cyanide [PDF]
Molecules, 2023 The orientation and magnitude of the molecular electric dipole moment are key properties relevant to topics ranging from the nature of intermolecular interactions to the quantitative analysis of complex gas-phase mixtures, such as chemistry in ...

A Unified Asymptotic Theory of Supersonic, Transonic, and Hypersonic Far Fields
Axioms, 2022 The problems of steady, inviscid, isentropic, irrotational supersonic plane flow passing a body with a small thickness ratio was solved by the linearized theory, which is a first approximation at and near the surface but fails at far fields from the body.

Clusters of organic molecules in a supersonic jet expansion [PDF]
The Journal of Physical Chemistry, 1985 A wide variety of clusters were obtained in seeded supersonic conical jet expansions of organic molecules. It was shown that mixed clusters probably are formed statistically in the collisional region of the expansion, although kinetic effects cannot be excluded.

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

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

Nucleation of copper during supersonic expansion [PDF]
, 1989 Nucleation of copper vapor during gas expansion in a supersonic nozzle is investigated. Time scales for nucleation delay and supersaturation doubling are considered in establishing the need for non-steady state nucleation theory. A population balance model is constructed for tracking the size spectrum of stable clusters formed from self nucleation and ...

Effect of Hydraulic Diameter on Potential Core Decay of Supersonic Jets [PDF]
INCAS Bulletin, 2020 Various studies dealing with decay characteristics of circular and noncircular supersonic jets were conducted by previous researchers. But in these studies due emphasis was not given to the hydraulic diameter (Dh), shape factor (ΞΆ) & the nozzle lip ...
