Flow and nematic director profiles in a microfluidic channel: the interplay of nematic material constants and backflow

Abstract:

We numerically and analytically study the flow and nematic order parameter profiles in a microfluidic channel, within the Beris–Edwards theory for nematodynamics, with two different types of boundary conditions—strong anchoring/Dirichlet conditions and mixed boundary conditions for the nematic order parameter. We primarily study the effects of the pressure gradient, the effects of the material constants and viscosities modelled by a parameter L2 and the nematic elastic constant L*, along with...
