Abstract:
The problem of flow of a non-Newtonian viscous fluid with power-law rheological properties
along a semi-infinite plate with a small localized irregularity on the surface is considered for large
Reynolds numbers. The asymptotic solution with double-deck structure of the boundary layer is
constructed. The numerical simulation of the flow in the region near the surface was performed
for different fluid indices. The results of investigations of the flow properties depending on the
fluid index are presented. Namely, the boundary layer separation is investigated for different
fluid indices, and the dynamics of vortex formation in this region is shown.
