Outline of Final Research Achievements

We have been developing the wall shear stress on the hydrogel surface to measure the velocity gradient near the wall. This technique has some remarkable characteristics as non-invasive, high spatial, high time and resolution. Especially the flow on opaque material surface was also measured using our present system due to measure the velocity fields above the flow surface. Using our technique we revealed that the hydrogel surface has a drag reduction because of a slip flow, and it increase with its swelling degree due to a pore size of polymer chain structure.
