| Abstract |
熱流動異相界面における分子吸着や反応・分離を支配するイオン層電位形成メカニズムの解明に向けて, 二波長自発ラマンイメージングによる熱流動界面の温度時空間分布および速度・温度時空間分布の非侵襲同時センシング法, エバネッセント波照射自発ラマンイメージング法による固液界面極近傍の濃度分布非侵襲センシング法, そして非線形ラマン散乱光を用いた電解質溶液中多種イオン群濃度分布非侵襲センシング法の開発を行った。マイクロデバイス内に蛍光プローブを混入することなく, 非侵襲にて異相界面における熱流動の速度, 温度や濃度分布を計測することが可能となった。
This research work focused on the development of non-intrusive sensing technique of thermofluid dynamics in order to investigate molecular absorption and formation mechanism of ion layer in the vicinity of interface between different phases. The following techniques were proposed in this work: (i) spatiotemporal distribution of temperature in microchannel by two-wavelength spontaneous Raman imaging, (ii) spatiotemporal distribution of velocity and temperature in microchannel by two-wavelength spontaneous Raman imaging, (iii) molecule concentration distribution in the vicinity of liquid-solid interface by total internal reflection spontaneous Raman imaging and (iv) ion concentration distribution in microchannel by coherent anti-Stokes Raman scattering. It can be concluded that non-intrusive measurements of velocity, temperature and concentration were achieved by Raman scattering, which means that fluorescent particles and dye are no longer required.
