Exempel på hur man kan använda VORTEX i en mening

• The parameter is named after Vincenc Strouhal, a Czech physicist who experimented in 1878 with wires experiencing vortex shedding and singing in the wind.
• Driven by "the most terrible hurricane that ever came out of the heavens", their ship was caught in the vortex.
• In fluid dynamics, a vortex (: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved.
• The warming is preceded by a slowing then reversal of the westerly winds in the stratospheric polar vortex, commonly measured at 60  ° latitude at the 10 hPa level.
• Anatoly Dorodnitsyn (1910–1994) – researched meteorology, vortex wing theory, boundary layer theory in a compressible gas, and supersonic gas dynamics.
• A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car.
• The buoyant mass of gas rises rapidly, resulting in turbulent vortices curling downward around its edges, forming a temporary vortex ring that draws up a central column, possibly with smoke, debris, condensed water vapor, or a combination of these, to form the "mushroom stem".
• Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it.
• Hoerner was a pioneer researcher in the field, having written a technical paper published in 1952 that called for drooped wingtips whose pointed rear tips focused the resulting wingtip vortex away from the upper wing surface.
• The renovation features accessibility, a warming kitchen, WiFi, a pool with beach entry, bubblers, current channel, vortex, fountains, separate splash pad, lap lanes, landscaped deck environment, and concessions.
• The idea that a form of turbulence might be possible in a superfluid via the quantized vortex lines was first suggested by Richard Feynman.
• Khazar reveals that it was he who sent the vortex and requests assistance against another god, Lethys, Nemesis' underling, in exchange for resources to rebuild the village.
• Mesovortex, a small scale vortex aloft within atmospheric convection, such as squall lines and tropical cyclones.
• In evolutionary genetics, mutational meltdown is a sub class of extinction vortex in which the environment and genetic predisposition mutually reinforce each other.
• " René Descartes wrote in his Discourse on the Method, relating the phenomenon to his vortex theory: "One can see by experience that water that has been kept on a fire for a long time freezes faster than other, the reason being that those of its particles that are least able to stop bending evaporate while the water is being heated.
• The extended formations (V formation) or "skeins" in which many migratory birds (especially geese) fly enable the birds (except, of course, the bird at the front) to use vortex surfing to take advantage of one another's vortices.
• •3: separated unsteady flow, having a laminar flow boundary layer upstream of the separation, and producing a vortex street,
  .
• Among them were the C-140 Jetstar Laminar Flow Control, F-111 Mission Adaptive Wing, F-14 Variable Sweep Flow Transition, Space Shuttle orbiter drag chute and F-111 crew module parachute tests with the B-52, and X-29 vortex flow control.
