Flow of Bingham plastic model in Fluent 6.3
Hi all.......
I am trying to simulate flow in Lid-driven cavity at Re=100,for bingham numers=0.01,0.1 and 1.
I am using Herschel bulkley model for viscosity. I am taking
square cavity of side L=1m
consistency index=1,n=1,yeild stress threshold=1e-4,
yieling viscosity=0.1 For bimgham number=0.01

But my results are not matching with literature values.

can somebody help me in this regard?
am i using wrong parameter values or do i need to write udf for viscosity?

please help me with this.
