Abstract
In this paper, the importance of non-Newtonian effects of a lubricant flow through a T-shaped microchannel with a moving lead are investigated. The lubricant flow isrepresented by Navier-Stokes equation for viscous, incompressible and steady fluid flows.Non-Newtonian characteristics are simulated by FENE-P constitutive equation. Finite Volume method was used to solve the case numerically. PSD distribution for Reynolds number Re=0.01 and Weissenberg number We =1 were compared with Newtonian case. Clear numerical evidence of a higher stresses for non-Newtonian case is discussed.
