Mr. Yuya OTAKA, of the College of Science and Engineering, won the Best Presentation Award at the 49th Information Visualization Symposium
Mr. Yuya OTAKA (Graduate School, College of Science and Engineering, Master's Program, Machine creation course 2nd Year) under the guidance of Professor Koji FUMOTO (Thermal-Fluid Control Laboratory) made an oral presentation on self-excited oscillating heat pipes in a lecture titled "Visualization of Thermal-Fluid Flow in Self-excited Oscillating Heat Pipes Using Temperature-Sensitive Paint" at the 49th Visualization Information Symposium held online from September 9 (Thursday) to 11 (Saturday), 2021, and received the Best Presentation Award.
Heat generation is a bottleneck in the development of artificial satellites and all kinds of electronic equipment, raising expectations of the development of cooling technology . Self-excited oscillating heat pipes are expected to be put into practical use because of their high efficiency heat transport without external power, but extremely complicated flow fields are generated internally, which makes it impossible to accurately design them.
In this research , Mr. OTAKA visualized the internal flow and temperature fields , and summarized and presented characteristics of thermal hydraulics that had never been measured before. In addition to the results, the easy-to-understand slides and clear explanations of the presentation were also highly rated.
