| Outline of Final Research Achievements |
In the present research, we have successfully measure the velocity of test fluid in a small-scale channel by using electron scanning microscope (SEM) through a thin film. The velocity was obtained by tracking a particle. Previously, the velocity measurement was carried out in a open channel flow having a free surface. However, in our study, we have employed a thin film which transmit a electron beam as a lid of the channel.
Furthermore, we have measured a velocity profile using a regular fluorescent microscope for various soft materials in a small-scale inner-flow. As a result, we have found that a large velocity slip on solid wall and that the magnitude of slip depends on the ionicity of soft material. We have observed only the near region of the wall and have quantitatively examined the slip by evanescent light.
