horseshoe vortex वाक्य

उदाहरण वाक्य

1. The "'horseshoe vortex "'model is a simplified representation of the vortex system of a wing.
2. In hydrodynamics, a form of horseshoe vortex forms around bluff bodies in the flowing water, for instance around bridge piers.
3. Three-dimensional lift and the occurrence of wingtip vortices can be approached with the concept of horseshoe vortex and described accurately with the Lanchester Prandtl theory.
4. Nevertheless, the simpler horseshoe vortex model used with a reduced effective wingspan but same midplane circulation provides an adequate model for the flows induced far from the aircraft.
5. Approximate theories for the lift distribution and lift-induced drag of three-dimensional wings are based on such analysis applied to the wing's horseshoe vortex system.
6. Hairpin vortices resemble the horseshoe vortex, which exists because of perturbations of small upward motion due to differences in upward flowing velocities depending on the distance from the wall.
7. The horseshoe vortex model is unrealistic in that it implies a constant circulation ( and hence, according to the Kutta Joukowski theorem, constant lift ) at all sections on the wingspan.
8. Instead of only one horseshoe vortex per wing, as in the lifting line theory, the VLM utilizes a lattice of horseshoe vortices, as described by Falkner in his first paper on this subject in 1943.
