Besides, when the fluid has a low viscosity, the flow experiences a high turbulence which may promote the formation of vortices. The presence of vortices in an impeller influences the velocity fields and increases the energy losses due to the turbulent dissipation, classified as a type of ...

His war diplomacy, however, quickly hit some major turbulence, as the British parliament, not eager to repeat its Iraq and Afghan misadventures, voted the once inconceivable — a straightforward, resounding no to joining yet another misguided American battle plan. France was soon backing out as we...
Watts backs away from the collapse, thrusters whirring to keep her out of the turbulence. A cloud of silt clears. In her floodlight beams, the OBELISK stands revealed - its outlines worn by the ages. Easily thirty feet tall. Watts stares at the obelisk, stunned. Her voice is husky: ...
valuable that you could introduce into your life than chanting. It’s been practiced for centuries in so many different faiths but is especially powerful in the Hindu tradition, where the Shastras and gurus have extolled the virtues of chanting God’s name as an anchor in the turbulence of ...
Then in dismay, I observed the walls of my apartment appeared to be swaying – not alarming because it was swaying gently and it felt like being on a plane flying through a patch of turbulence. So I was calm, although by now, the word “earthquake” sprang to mind. As I was seated ...
A flat surface could be used instead of an airfoil section but it is not nearly as effective – Look at the flat fan blades on cheap cooling fans: they create noise from turbulence and don’t move the air as efficiently. [Revision Needed] “A beautifully simple demonstration of the Bernoul...
(average height of the top of well mixed MABL capped by a temperature inversion), while under stable conditions this was set to 250 m, which is the average height of the low level wind jet (LLJ) (near zero shear and low turbulence) that was usually observed in sounding legs under these...
The foundation design can also influence the target natural frequency of the whole system, which needs to avoid the 1P range. Simplified models often idealize the tower as a beam, and the RNA as a lumped mass with or without a rotational inertia. The foundation is often idealized as ...
Ten different confluences from 45∘∘ to 90∘∘ were simulated to study the effects of the junction angle on the flow structure, using a numerical code that solves the 3D Reynolds Averaged Navier-Stokes (RANS) equations with the k-𝜖ϵ turbulence closure model. The results showed ...
