Eksempler på viscous

• Note that this phenomenon has a purely inertial character; viscous forces cannot prevent it, although these forces guarantee the space regularity of the solution.

• For small values of s the viscous stresses on the near wall dominate and produce a thrust in the positivex direction.

• As the industrial process involves large shear stresses, fibres will slip over one another, and we assume the material to be an anisotropic viscous continuum.

• Ultimately sufficiently high wavenumbers are excited that the viscous forces begin to bite, and the dissipation rate then builds up.

• This is equivalent to the assumption that above k, a total dissipation of the turbulent energy takes place due to the viscous forces.

• This is done using an energy principle based on equating the viscous flow dissipation with the released surface energy.

• They performed an extensive set of experiments studying steady and unsteady viscous jet behaviour.

• This is in striking contrast to the familiar downstream growing boundary layer and downstream viscous wake existing when the fluid is homogeneous.
