viscous flow उदाहरण वाक्य
उदाहरण वाक्य
- Thus, thermal motion in liquids can be decomposed into elementary rigidity while a liquid yields to macroscopic viscous flow in response to the application of an applied shearing force is accepted by many as the mechanical distinction between the two.
- Glasses containing both boron and phosphorus ( borophosphosilicate glass, BPSG ) undergo viscous flow at lower temperatures; around 850 �C is achievable with glasses containing around 5 weight % of both constituents, but stability in air can be difficult to achieve.
- The viscous flow in amorphous materials is characterized by a deviation from the Arrhenius-type behavior : changes from a high value at low temperatures ( in the glassy state ) to a low value at high temperatures ( in the liquid state ).
- Lobate convex features on the surface known as "'viscous flow features "'and "'lobate debris aprons "', which show the characteristics of non-Newtonian flow, are now almost unanimously regarded as true glaciers.
- Viscous flow near grain boundaries, for example, can give rise to internal slip in the direction of any lattice plane containing the dislocation, while the principal driving force for " dislocation climb " is the movement or diffusion of vacancies through a crystal lattice.
- Inviscid flow was further analyzed by various mathematicians ( Leonhard Euler, Jean le Rond d'Alembert, Joseph Louis Lagrange, Pierre-Simon Laplace, Sim�on Denis Poisson ) and viscous flow was explored by a multitude of engineers including Jean L�onard Marie Poiseuille and Gotthilf Hagen.
- I suspect there will also be problems with moving fluids, such as in viscous flow, or in boundary layers, but I don't recall any examples, though we know, for example, that Bernoulli's equation doesn't work for some non-ideal fluids.
- The Doremus criterion of fragility can be expressed in terms of thermodynamic parameters of the defects mediating viscous flow in the oxide melts : R D = 1 + H d / H m, where H d is the enthalpy of formation and H m is the enthalpy of motion of such defects.
- :A model proposed by Schmincke et al . ( 1967 ) and later supported by Chapin et al . ( 1979 ), based on observations on the Wall Mountain Tuff, suggests that the rheomorphic structures such as a pervasive pyroclasts were formed during laminar viscous flow as the density current comes to a halt.
- While the no-slip condition is used almost universally in modeling of viscous flows, it is sometimes neglected in favor of the'no-penetration condition'( where the fluid velocity normal to the wall is set to the wall velocity in this direction, but the fluid velocity parallel to the wall is unrestricted ) in elementary analyses of inviscid flow, where the effect of boundary layers is neglected.
