Study of the Wall Slip Effect on Viscous Fluid Micro-Extrusion Process

Abstract:

In micro-scale flow condition, the flow rate and fluid extrusion expansibility are always affected by the wall slip between the fluid and tube wall. In this research, a wall slip model based on a micro-tube flow was developed, and then the wall slip effect on the viscous fluid micro-extrusion process was explored by computational fluid dynamics (CFD) with different extruding pressures. The results showed that wall slip make the fluid resistance and expansibility decrease, and the fluid mass flow rate increase.
