Project SQUID, Some Properties of Shock Relaxation in Gas Flows Carrying Small Particles.
TL;DR: In this paper, the effects of varying the shock strength or the properties of the mixture are investigated theoretically, and it is noted that some flow variables do not always change monotonically throughout the relaxation zone but may go through a maximum or minimum.

Vortex Shedding from a Circular Cylinder in Moderate Reynolds-Number Shear Flow
TL;DR: In this paper, the frequency of vortex shedding from a circular cylinder in a uniform shear flow and the flow patterns around it were experimentally investigated and the critical Reynolds number beyond which vortex shedding occurred was found to be higher than that for a uniform stream and increased approximately linearly with increasing shear parameter.

Evaluation of a method for heat transfer measurements and thermal visualization using a composite of a heater element and liquid crystals
TL;DR: In this article, a composite consisting of a plastic sheet coated with liquid crystal, another sheet with a thin layer of a conducting material (gold or carbon), and copper bus bar strips were evaluated and found to provide a simple, convenient, accurate, and low-cost measuring device for use in heat transfer research.

The lift on a small sphere in a slow shear flow
TL;DR: In this article, it was shown that a sphere moving through a very viscous liquid with velocity V relative to a uniform simple shear, the translation velocity being parallel to the streamlines and measured relative to streamline through the centre, experiences a lift force 81·2μVa2k½/v½ + smaller terms perpendicular to the flow direction, which acts to deflect the particle towards the streamline moving in the direction opposite to V.
Journal ArticleDOI
The structure of turbulent boundary layers
TL;DR: In this article, the authors describe the formation of low-speed streaks in the region very near the wall, which interact with the outer portions of the flow through a process of gradual lift-up, then sudden oscillation, bursting, and ejection.
Journal ArticleDOI
An investigation of particle trajectories in two-phase flow systems
S. A. Morsi,A. J. Alexander +1 more
TL;DR: In this article, the authors describe a theoretical investigation into the response of a spherical particle to a one-dimensional fluid flow, and the motion of the spherical particle in a uniform 2D fluid flow about a circular cylinder.
Journal ArticleDOI
The production of turbulence near a smooth wall in a turbulent boundary layer
TL;DR: In this paper, the structure of the flat plate incompressible smooth-surface boundary layer in a low-speed water flow is examined using hydrogen-bubble measurements and also hot-wire measurements with dye visualization.
Journal ArticleDOI
New aspects of turbulent boundary-layer structure
TL;DR: For the zero-pressure-gradient turbulent boundary layer over the Reynolds-number range 500 2000, say, the layer appears to consist very largely of elongated hairpin vortices or vortex pairs, originating in the wall region and extending through a large part of the boundary layer thickness or beyond it; they are for the most part inclined to the wall at a characteristic angle in the region of 40-50°.
