Squeeze film flow of ideal elastic liquids

摘要: Abstract An exact solution is presented for the squeeze film flow of an Oldroyd B. fluid. The demonstrates that kinematics similar to Newtonian (or Maxwellian) one. Theoretical predictions constant velocity squeezing are compared experimental observation well characterized non-shear thinning elastic fluids. It shown both theoretically and experimentally effect elasticity in a always reduce load relative inelastic (Newtonian) prediction this reduction falls between upper lower asymptote by B given Stefan viscosity polymer solvent. Experimental observations agree with theoretical fluid at low shear rates where it steady dynamic properties test fluids used program represented constitutive equation. With exception work Lee et al. [6] Maxwell fluid, represents one few cases large effects due indeed predicted equation which actually describes program.
