| Popis: |
The heat transfer mechanism at the materials interface, such as gas-liquid, liquid-liquid, and solid-liquid interface, gives great insight into understanding the geometrical change in the interface over time. The temperature- and velocity-field measurements with respect to the liquid as the target material are essential to study the mechanism in spatiotemporal manner without disturbing an interaction region of the liquid. The simultaneous thermometry and velocimetry methods for non-aqueous liquid are studied and introduced based on the laser-induced fluorescence (LIF) and particle imaging velocimetry (PIV). Toluene is chosen as a non-aquatic liquid in which two different luminophores are dissolved. These two luminophores as well as the PIV particle emit at different wavelengths that are simultaneously acquired through three color channels of a high-speed color camera. The measurement system satisfying the proposed method is discussed and validated in a natural convection flow. |
