Abstract

The role of the elasticity of the fluid is investigated in a squeeze film flow, between two parallel coaxial disks. An analysis is done for elastic fluids of low Deborah numbers, where the stress relaxation process is a first order effect to the dominant zero order effect of the viscosity. The constitutive equation of the fluid does not consider the normal-stresses. The results, which show a reduction in the load capacity for a steady speed squeeze action, are consistent with previous experiments in oilpolymer solutions. An improvement in the lubrication performance at dynamic loads is predicted and unlike in Newtonian fluids, the acceleration of the upper disk has a significant effect. © 1987 by ASME.
