Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
Australian soldiers in a front-line trench during World War I.Photograph taken by Capt. F. Hurley, sometime between August 1917 and August 1918.. A front line (alternatively front-line or frontline) in military terminology is the position(s) closest to the area of conflict of an armed force's personnel and equipment, usually referring to land forces.
The Gaussian air pollutant dispersion equation (discussed above) requires the input of H which is the pollutant plume's centerline height above ground level—and H is the sum of H s (the actual physical height of the pollutant plume's emission source point) plus ΔH (the plume rise due to the plume's buoyancy).
The ash is sucked into the engines, where it is melted by the heat of the engine, Power said. The melted ash then coats the inside of the engine, ultimately leading to engine failure.
A plumb bob. A plumb bob, plumb bob level, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical direction as a reference line, or plumb-line. It is a precursor to the spirit level and used to establish a vertical datum. It is typically made of stone, wood, or lead, but can also be ...
A pilot on a Hawaiian Airlines flight said a plume-like cloud “shot” in front of the plane moments before severe turbulence last month, federal officials said Friday.
Plume (feather), a prominent bird feather; Plume (fluid dynamics), a column consisting of one fluid moving through another fluid; Eruption plume, a column of volcanic ash and gas emitted into the atmosphere during an eruption; Mantle plume, an upwelling of hot rock within the Earth's mantle that can cause volcanic hotspots
