Flow properties of a polymeric solution
Figure 1: Evolution of birefringence (top) and flow patterns (bottom) as the flow rate is increased from left to right. Flow enters the 4-way junction through top and bottom channels and exits through the left and right-hand channels. At low flow rate (left) flow is stable and symmetric. As the flow rate increases, the birefringence indicates stretching of the polymer and the flow patterns become increasingly distorted.
