TLDR
A fluid is a substance in which the constituent molecules are free to move relative to each other, and in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure.Abstract:
A fluid is a substance in which the constituent molecules are free to move relative to each other Conversely, in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure While these definitions classify matter into fluids and solids, the fluids subdivide further into liquid and gasesread more

Compressible subsonic flow on a staggered grid
TL;DR: The method works well in modelling flows in the subsonic range that normal incompressible techniques do not capture and where compressible methods are inefficient, and is investigated adapting these techniques to granular elastic-plastic flow.

Microfocal X-ray computed tomography post-processing operations for optimizing reconstruction volumes of stented arteries during 3D computational fluid dynamics modeling

TL;DR: Post-processing operations used in conjunction with microfocal X-ray CT imaging and reconstruction are presented to generate geometrically accurate flow domains within the localized region of a stent several weeks after implantation to test the hypothesis that reductions in normalized wall shear stress (WSS) and increases in the spatial disparity of WSS immediately after stent implantation may spatially correlate with the temporal development of NH within the stented region.

Subaqueous "yardangs": Analogs for aeolian yardang evolution
TL;DR: In this article, the geometries of the "yardangs" are described and related to semi-lemniscate shapes that minimize hydraulic drag, and a semi-quantitative model for landform evolution is proposed.

The effect of spark timing on residual gas fraction
TL;DR: The Effect of Spark Timing on Residual Gas Fraction was studied in this article, where the effect of timing on the residual gas fraction was investigated and the results showed that the effect was negligible.

Experiments with Fluid Friction in Roughened Pipes
C. F. Colebrook,C. M. White +1 more
TL;DR: Nikuradse as discussed by the authors showed that the resistance law of the Karman-Prandtl theory for smooth surfaces was satisfactorily satisfied with respect to the size of roughness grains.
