Exempel på nip

• This is perhaps not surprising since, though the flux through the nip is different, the film-splitting behaviour (equation 1.1) is the same.

• Two large floes were grinding and the ship was nipped twice and lifted several feet.

• He imposed both ingoing film thicknesses in terms of the total flux through the nip and an inlet film thickness ratio.

• By exploiting the thin-layer limit suggested by the geometry of the nip, the problem is reduced to a nonlinear convection-diffusion equation with one free boundary.

• The distribution of pressure, velocity and felt porosity in the nip have therefore traditionally been matters of great debate.

• Guided by the above literature, we propose an ensemble-averaged multiphase model which will be applied to the flow in a roll press nip.

• The guide rolls collapse the film from a tubular shape and the nip rolls seal the top edge of the bubble.

• Fortunately the air was calm; a nip in this heavy ice might have been fatal.

• He also said that another similar case was brewing, which, because of this case, will be effectively nipped in the bud.

• The upstream meniscus was observed to move inwards and through the nip (where the gap width is minimum) with the two-dimensional flow remaining stable.

• As the paper sheet and fabric enter the nip region, both are compressed.

• The exact expression for the total amount of water squeezed out by the nip is preserved by the numerical solution.

• Although we aim to have proposed a coherent model for the flow in a roll press nip, much work remains to be carried out.

• This happens many times and in many different ways to a single portion of the paper sheet; we shall examine a single pass through such a 'roll press nip'.

• The nip rolls form an airtight seal, so that between them and the die the film forms a tubular bubble containg air at a pressure slightly above atmospheric.
