Impact of expansion level on flowfield with sudden expansion at supersonic regimes [PDF]
Materials Today: Proceedings, 2021 Abstract This paper aims to assess the control mechanism's efficiency and flow pattern in the pipe. The flow was investigated for Mach numbers M = 1.25, 1.3, 1.48, 1.6, 1.8, 2.0, 2.5, and 3.0 for a step height of 3 mm. The NPRs of the tests were from 11 to 3.

Annular Supersonic Ejector Design and Optimization [PDF]
, 2012 An ejector is a device that entrains a secondary flow into a high speed stream that is generated by expansion of high pressure motive gas [1]. These ejectors can be broadly classified into central ejectors and annular ejectors.

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 ...

Laser spectroscopy of supersonic expansions of ICL
Journal of the Chemical Society, Faraday Transactions 2, 1982 High-resolution fluorescence excitation spectra of the B3Π(0+)–X1Σ+ system of ICl, rotationally cooled in a seeded supersonic expansion, have been obtained using a single-mode c.w. dye laser. Problems due to overlap with ICl(A–X) and contaminant I2(B–X) bands, are significantly reduced by the extreme cooling and a number of previously unreported ICl(B ...

Spatial mapping of low pressure cluster jets using Rayleigh scattering
Scientific Reports, 2023 In this work, we report evolution of atomic clusters in a highly under-expanded supersonic jet of Argon. A high resolution and sensitive Rayleigh scattering based experimental set-up is designed to overcome the limitations encountered in conventional set-
