| Outline of Annual Research Achievements |
Characterizing, and understanding the causes of, flow instabilities and bifurcations is vital for the development of fluidic systems with optimal performance. In Newtonian fluids, vortices are a ubiquitous hallmark of flow complexity and turbulence driven by inertial effects. We have been using various microfludic platforms to examine the dynamics of the formation and breakdown of streamwise vortices generated in common flow configurations (T- and X-shaped junctions) at small length scales. We have also made new contributions by the development of unique microfluidic cylinder geometries and also of wavy-walled microchannels designed for the study of spanwise vorticity dynamics. Finally, we developed nanofluidic platform to make nanoparticles and studied nanoscale immunoassay problems.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
FY2018 has been a very productive year. We are able to publish 8 peer reviewed papers related to this funding and made great progress to use microfluidics to study a variety of flow and materials related problems.
|
| Strategy for Future Research Activity |
For FY2019, we hope to strengthen our existing research areas, and introduce new initiatives and directions related to this Kakenhi project. We will leverage state-of-the-art microfabrication facilities at OIST to push the study of both Newtonian and viscoelastic flows in new geometrical regimes. In addition, we plan to develop new experimental and imaging techniques in microfluidics, especially those having technological relevance.
|
| Causes of Carryover |
Since OIST has institute open access fee discount with several publishers, we are able to spend less on the original requested publication fees. We will use this carryover amount to pay for the new publication fees in FY2019.
