Flow past a sphere at the free-surface using URANS

, 2013
The flow past a sphere located at the free-surface, was studied over the critical Reynolds number range: 2x10^5 to 4x10^5. Experiments were carried out in the Lamont tank at the University of Southampton.

Obstacle Geometry Effect on the Stability of Two-Dimensional Incompressible Flow in a Channel

Journal of Applied Fluid Mechanics, 2016
Two-dimensional incompressible fluid flow around a rectangular shape placed over a larger rectangular shape is analyzed numerically. The vortex shedding is investigated at different arrangements of the two shapes.

The Universal Presence of the Reynolds Number

Fluids
The Reynolds number is a fundamental parameter in fluid dynamics, initially introduced by O. Reynolds in 1883 to characterize the transition between laminar and turbulent flow in fluids and necessary in the scaling of viscous resistance.

Optimum Shape of Critical Nozzles on Low Reynolds Numbers

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2011
For toroidal throat Venturi nozzles with various diffuser lengths and half angles, the behaviors of their critical back pressure ratios were experimentally investigated on the Reynolds number less than 2×104 . The results showed that the diffuser shapes provided in JIS Z 8767(2006) are not always adequate for flow measurements under the above Reynolds ...

Steady Flow of Purely Viscous Shear-Thinning Fluids in a 1:3 Planar Gradual Expansion

Journal of Applied Fluid Mechanics, 2019
Laminar flow of non-Newtonian fluid (shear-thinning) through a 1:3 planar gradual expansion is numerically investigated, for various Power-Law index (0.6, 0.8 and 1.0) and expansion angles (15, 30, 45, 60 and 90°) at different generalized Reynolds number

The Aerodynamics of New Design Soccer Balls Using a Three-Dimensional Printer

Applied Sciences
Eight balls were manufactured with a 3D printer to resemble various types of 32-panel soccer balls. One ball was completely smooth, whereas the other seven possessed various dimple patterns on their surface panels.
