Handle and control micron/sub-micron system accurately with precise flow control and understanding fluid properties
Investigate the flow patterns in the 4:1 micro-contraction channel as elasticity increases
Define transient vortex, its types and characteristics in microchannel flow using highly elastic fluid
Rheology of viscoelastic fluid
With higher fluid elasticity, transient vortex tends to be more asymmetric.
As Wi increases, the size of oscillating vortex increases in vortex growth region (D) and in transient vortex region (E)
Period of oscillating vortex (both symmetric and asymmetric) falls in between 2 to 6 s
