Calendering analysis of a third-order fluid

Abstract

In this paper, the study of a non-Newtonian material when it is dragged through the narrow region between two co-rotating rolls is carried out. The conservation of mass and momentum equations based on lubrication theory are nondimensionalized and solved for the velocity and pressure fields using the perturbation technique. By considering the influence of the material parameter, the dimensionless leave-off distance in the calendering process is determined. The leave-off distance is expressed in terms of eigen value problem. Quantities of engineering interest like maximum pressure, the roll-separating force, and the power transmitted to the fluid by rolls are calculated. It is observed that the material parameter has great influence on detachment point, velocity, and pressure distribution, which are useful for the calendering process.

“…In the upper stream and downwards sections of graphs, velocity and transport is affected and obstacled whereas in the middle nip section the drag flow is supported due to the poignant roller and sheet. The support or disagreement enhances as coupled stress rises [23][24][25][26][27].…”
