| 研究実績の概要 |
Continuous investigations are carried out on the flow structure and spreading dynamics of three phase contact line (TPCL) with full consideration of thermophysical properties across phases. Specifically, I formulate an efficient mathematical model for capturing the dominating physics, and apply trajectory analysis and infrared thermography to reveal the transition of internal flow and temperature distribution. A phase diagram is derived to describe the transition of flow state due to the competition of Marangoni flow, capillary flow, and evaporation flux, which in cases leads to the formation of stagnation point near TPCL. The spatiotemporal variations of capillary and Marangoni velocity are further quantified by mathematically decomposing the tangential velocity of interfacial flow.
