Journal ArticleDOI
Free underexpanded jets in a quiescent medium: A review
TL;DR: In this article, the authors present an exhaustive overview of the main experimental papers dealing with underexpanded jets, from those where there is clearly a lack of confidence, and some clues are given on the numerical methods that may be used if one wants to study such jets numerically, together with an emphasis on the specific thermodynamic difficulties associated to this kind of extreme conditions.
Journal ArticleDOI
Effects of axisymmetric sonic nozzle geometry on Mach disk characteristics
Journal ArticleDOI
Scaling parameters for underexpanded supersonic jets
TL;DR: In this paper, a set of expressions were developed for afterexpansion equivalent jet exit diameter, velocity, temperature, and density to allow for a better collapse of jet spreading and centerline decay rates.

Review on hydrogen safety issues: Incident statistics, hydrogen diffusion, and detonation process
Fuyuan Yang,Wang Tianze,Deng Xintao,Dang Jian,Zhaoyuan Huang,Hu Song,Yangyang Li,Minggao Ouyang +7 more
TL;DR: In this article, the authors review the key issues concerning hydrogen safety, including hydrogen incident investigation, hydrogen leakage and diffusion, hydrogen ignition, and explosion, in combination with a practical survey analysis.
Journal ArticleDOI
Structure of Turbulent Sonic Underexpanded Free Jets
TL;DR: In this paper, the authors used laser-induced iodine flourescence and mean and fluctuating streamwise velocities using laser Doppler anemometry to predict turbulent mixing in fully developed pipe flows injected into still air.

On the Structure of Jets from Highly Underexpanded Nozzles Into Still Air
Thomas C. Adamson,J. A. Nicholls +1 more
TL;DR: In this article, the position of the first normal shock in the jet behind a highly underexpanded nozzle is calculated using axial pressure distribution on the centerline of the flow behind the orifice, calculated by the method of characteristics, and the shock is then assumed to exist at that point where atmospheric pressure would be attained behind the shock.

Viscous Hypersonic Flow Past a Slender Cone
TL;DR: In this paper, the strong interaction region in viscous hypersonic flow past a slender cone is considered and expressions for the pressure, shock, skin friction, and heat transfer are derived.
