Effect of geometry error on the non-Newtonian flow in the ceramic microchannel molded by SLA

Abstract The ceramic microchannel manufactured by stereolithography (SLA) can be used in many engineering cases. SLA is an accurate 3D printing technology, while the small geometry error inevitable. involved flow always non-Newtonian fluids. Therefore, it necessary to analyze Bingham fluids with errors. To conduct numerical simulations, a modified lattice Boltzmann (LB) model presented. Then, good consistency between theoretical and solutions demonstrates effectiveness of improved method. required cases are analyzed using proposed Both streamlines outlet velocity distribution show that increases velocity. parameters important factors microchannel.
