Squeezing Flow of a Power Law Fluid Between Grooved Plates

Abstract

Surface microchannels can accelerate squeezing flow of a fluid in a thin gap between parallel plates. Using a computational model and restricting attention to power law fluid, a parametric study is made of the influence of channel size for a certain family of channel patterns, with results tabulated for general use. An approximate heat conduction model is used to estimate the effect of channel size and pattern on resistance to heat flow normal to the fluid layer.
