Ghost effect from Boltzmann theory
Communications on Pure and Applied Mathematics, EarlyView.Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Design and CFD Simulation of Supersonic Nozzle by Komega turbulence model for Supersonic Wind Tunnel [PDF]
E3S Web of ConferencesThis paper presents an impressive design of a convergent divergent (C-D) nozzle using the method of characteristics for a Mach number 2 test section. The nozzle’s geometry was meticulously crafted in SolidWorks, and its performance was evaluated through ...

Altitude performance of a low-noise-technology fan in a turbofan engine with and without a sound suppressing nacelle [PDF]
Test variables were inlet Reynolds number index (0.2 to 0.5), flight Mach number (0.2 to 0.8), and flow distortion (tip radial and combined circumferential - tip radial patterns). Results are limited to fan bypass and overall engine performance.

European Journal of Organic Chemistry, EarlyView.The parent 5,5′‐binaphtho[2,1‐d]isoxazole and its 3,3′‐dimethyl and 3,3′‐diphenyl derivatives are synthesized via condensation of the respective dicarbonyl compounds with hydroxylamine, followed by cyclodehydration of the resulting dioximes. The dicarbonyl precursors are obtained through 4‐ or 6‐step sequences from 1‐naphthol or 1‐naphthaldehyde ...

Flight investigation of XB-70 structural response to oscillatory aerodynamic shaker excitation and correlation with analytical results [PDF]
The low frequency symmetric structural response and damping characteristics of the XB-70 airplane were measured at four flight conditions: heavyweight at a Mach number of 0.87 at an altitude of 7620 meters (25,000 feet); lightweight at a Mach number of 0.

Energy Science &Engineering, EarlyView.ABSTRACT The turbulent flow between coaxial cylinders, particularly when the inner cylinder is rotating, exhibits complex hydrodynamic and heat transfer behaviors critical for various engineering applications. Although many previous studies have simplified these systems with idealized assumptions, real‐world scenarios involve mixed convection and ...
