| Abstract(J) | 本研究ではMEMS技術を用いて薄膜抵抗体式センサを開発し，エンジン壁面での熱流束測定を行った．その結果，熱流束はサイクルごとに大きく変動することを明らかとした．さらに，熱流束変動から移流速度を推定する手法を開発した．PIVとの比較から，推定された移流速度が速度境界層外縁付近の流れに対応することを明らかにした． Translation |
| Abstract(E) | To mitigate cooling losses, it is necessary to investigate the heat transfer mechanisms on engine walls. The authors developed a thin-film resistance type sensor with MEMS technologies and measured wall heat flux in an engine. As a result, the MEMS sensor clearly detected the heat flux, and it was found that the heat flux varied widely for each cycle. In addition, advection velocity was estimated from the heat flux fluctuations. By comparing the MEMS to PIV, it was found that the estimated advection velocity corresponded to the flow near the outer edge of the velocity boundary layer. |
