My aim was to capture the variation in velocity profile for flows at different viscosity values. I’m assuming the normalised shape of the velocity profiles is going to change given different lattice viscosities, and have implemented a code to demonstrate this. However at different viscosity values the normalised velocity profile (U/Umax) are identical for each case.
The velocity magnitudes are higher with a less viscous fluid, but I was expecting the shape of the normalised profiles to vary which does not seem to be the case. I have a feeling this may just be the way fluid flows work but can someone confirm this for me?
