Abstract

In the present study, a novel numerical algorithm based on combination of lattice Boltzmann method (LBM) and Smoothed Profile Method is used to investigate the motion of suspense circular particles in non-Newtonian power law fluid in shear flow. At first, the fluid velocity profile at different power law fluid indexes was analyzed and the results were compared with the numerical results of the previous works. In the present study, the rheological behavior of suspension with circular particles of same and different sizes randomly placed between parallel plates in shear flow was investigated in shear thinning and shear thickening medimum on the LBM framework and the effective viscosity was calculated for various Reynolds number and solid volume fraction (). For validation, the results of the relative viscosity were compared with the ones of previously works for Newtonian fluid and good agreement was observed.
