Note on the limits to the local Mach number on an aerofoil in subsonic flow [PDF]

, 1948
It has been noted in some experiments that the local Mach number just ahead of a shock wave on an aerofoil in subsonic flow is limited, values of the limit of the order of 1.4 are usually quoted.

Numerical Calculation of Convection with Reduced Speed of Sound Technique [PDF]

, 2012
Context. The anelastic approximation is often adopted in numerical calculation with low Mach number, such as stellar internal convection. This approximation requires frequent global communication, because of an elliptic partial differential equation ...

Surface Characterization of Scintillator‐Adsorbed Polyethylene Terephthalate Film and Its Use for Detecting α$$ \upalpha $$‐ and β$$ \upbeta $$‐Particles

Journal of Applied Polymer Science, EarlyView.
Thermal transfer using the high‐temperature crimping method led to the bonding of cellulose fibers and a scintillator to the film surface. β‐Particles of tritiated water were detected by immersing the scintillator‐adsorbed film. Scintillation images of the scintillator‐adsorbed film were obtained by irradiating β‐particles from 90Sr/90Y and α‐particles

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion

The Astrophysical Journal
We carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).

Nanosecond Hyperquenching for Electron Cryo‐Microscopy Without Air‐Water Interface Artifacts

Chemistry – A European Journal, EarlyView.
A novel method for the ultrafast vitrification of the biological assemblies is assayed by the electron cryotomography. Protein specimens prepared by this method inherently lack the spatial/structural artifacts, which derive from the surface tension at the air‐water interface (AWI).
