Moving Model Test of High-Speed Train Aerodynamic Drag Based on Stagnation Pressure Measurements. [PDF]
PLoS ONE, 2017 A moving model test method based on stagnation pressure measurements is proposed to measure the train aerodynamic drag coefficient. Because the front tip of a high-speed train has a high pressure area and because a stagnation point occurs in the center ...

Empirical equation of the Mach number as a function of the stagnation pressure ratio for a quasi-one-dimensional compressible flow [PDF]
FME Transactions, 2023 In the present work for a quasi-one-dimensional isentropic compressible flow model, an empirical equation of the Mach number is constructed as a function of the stagnation pressure ratio for an analytical equation that algebraic procedures cannot invert.

Conceptualisation of a novel electromechanical system for small-volume needle-free jet injection
Engineering Applications of Computational Fluid Mechanics, 2023 Needle-free jet injectors are minimally invasive drug delivery systems that utilise high-velocity microjets (∼100 m/s) created by pressurising the liquid drug through a micronozzle (50–300 µm in diameter).
