A nonlocal continuum mechanics formulation, which takes the small length scale effects into consideration, is ...
The water velocity will increase whenever the flow in an open channel passes over an obstruction like a broad crested weir, because of the decrease in cross-sectional flow area. Within limits, the higher the obstruction, the greater the water velocity will be going over the...
velocity vector of the fluid V e : exhaust air velocity (m/s) V s : supply air velocity (m/s) y + : dimensionless wall distance α 0 : horizontal deflection angle of air supply (°) β : volumetric expansion coefficient (K−1) ε : supply/exhaust ratio ε 0 : dissipa...
Vortices in fluid mechanics represent rotational structures of concentrated energy around a center where the fluid pressure and velocity is close to zero =-=[4, 5, 10]-=-. Centers of vorticity are surrounded by strong rotational flows. Smoothing vector fields as described in the previous section...

the hole inclination has a limited effect on the critical re-suspension velocity in hole sections with high inclination;the rotation of the drill pipe is helpful for the re-suspension of small-sized cuttings;in some extent,the smaller the value of drilling fluid and consistency factor are,the ...

The transition from laminar to turbulent flow depends not only on the velocity of the fluid, but also on itsviscosityand density and the geometry of the flow system. A parameter used to characterise fluid flow is theReynolds number. For full flow in pipes with circular cross-section, the Rey...
