Boundary layer in flow of Shear-dependent-viscosity fluids between parallel plates

POSTER

Abstract

Formation of the boundary layer in the laminar flow of Herschel--Bulkley fluid between parallel plates is taken into consideration . In particular, the study is focused on the flow of the shear thinning and shear thickening fluids past a partial vertical wall in between the plates. Upon numerically solving the continuity and momentum equations the flow is analyzed throughout the domain using a finite volume scheme. The shear stress at the wall together with velocity distribution are evaluated and compared with experimental results for several values of Herschel-Bulkley coefficients for fluidity and flow behavior index.
