The flow generated by a sphere descending uniformly in a linearly stratified diffusive fluid is investigated numerically for different Reynolds (Re) and Froude (F ) numbers. The parameters used for the simulations were 10 ≤ Re ≤ 10 and 10 ≤ F ≤ 10, keeping the Schmidt number, Sc (= 700, typical of sea water) fixed. The results demonstrate drag dependence on viscosity and stratification, suggest...

Analyze the data of Miami Heat in the NBA playoff season 2012-2013 from the aspects of team, main force, bench players, and core players to investigate the winning factors. The result shows that: Free throws and turnover of Miami Heat team are more than the opponents, while fouls are less; Two-point shooting number, three-point percentage and score of main forces are higher than the opponents; ...

In this article, we analyze a recently-presented scheme for singularly-perturbed systems of balance laws, the so-called Reference Solution Implicit Explicit scheme. RS-IMEX scheme’s bottom-line is to use the Taylor expansion of the flux function and the source term around a reference solution (typically the asymptotic limit or an equilibrium solution) to decompose the flux and the source into s...

The aim of this article was to compare swimming power output between boys and girls and to model the relationship between swimming power output and sprinting performance in young swimmers. One hundred young swimmers (49 boys and 51 girls, aged between 11 and 13 years) underwent a test battery including anthropometrics (body mass, height, arm span [AS], and trunk transverse surface area), kinema...

In an open channel, a hydraulic jump is a sudden transition from a high-velocity to slower, fluvial flow motion. The impinging flow forms a turbulent roller with a highly fluctuating free-surface, while a large amount of air bubbles is entrapped at the jump toe. The present work presents some physical investigations of hydraulic jumps based upon a wide range of inflow Froude numbers (3.8 < Fr1 ...
