viscosity nghĩa là gì

Ví dụ về viscosity

• In contrast, in the presence of viscosity, there is no such equivalence.

• Uncertainties in the magnetized plasma viscosity remain as an obstacle to unambiguous tests of the results in the case of real plasmas.

• Flow approaching the sphere from upstream accelerates, forms a vortex jump beyond the equator and then decelerates slowly downstream under the action of viscosity.

• There is a large increase in potential vorticity generated by the artificial viscosity, which again results in layers of enhanced static stability near the boundaries.

• The dynamical system is determined by travelling-wave solutions of the associated viscosity equation.

• For instance, the isotropic eddy viscosity hypothesis does not predict the observed fact that the shear stress and mean velocity gradient vectors have different directions.

• The viscosity dissipates the fluctuation energy with conservation of helicity.

• An alternative way of deriving a cutoff for (1.5) at high frequencies is to retain the effect of viscosity.
