ABSTRACT: Numerical simulation of the bifurcation of
Bingham fluid streamline topologies in rectangular double-lid-driven cavity,
with varying aspect (height to width) ratio A, is presented. The lids on the
top and bottom move at the same speed but in opposite directions so that
symmetric flow patterns are generated. Similar to the Newtonian case,
bifurcations occur as the aspect ratio decreases. Special to Bingham fluids,
the non-Newtonian indicator, Bingham number B, also governs the bifurcation
besides the bifurcation parameter A.
