Outline of Final Research Achievements

This report presents the development of measuring flow velocity and flow rate which is applicable to high temperature, high pressure and high corrosion conditions. The measurement system uses the pulsed ultrasound induced by the laser ultrasound and the transmitted pulse is detected by using the laser vibration meter. The flow velocity can be calculated by the delay time of the transmitted pulse. To estimate the developed measurement system, the actual scale flow measurements were conducted at the flow rate calibration facility in Japan. Additionally, a new signal processing technique for flow rate measurement using the ultrasonic velocity profile method was also developed.

Academic Significance and Societal Importance of the Research Achievements

超臨界地熱発電は、古火山・古カルデラ下部に存在する可能性が高い超臨界岩体の熱エネルギーを利用するため、地熱発電容量を現在の数十倍以上にできるポテンシャルを有する。超臨界地熱発電プラントの設計・運用には地熱貯留槽における「温度・圧力・流量」のセンシング技術が不可欠だが、唯一「流量」において将来的に実用化見通し可能な基盤技術が見当たらない。これは、超遠隔(4~5km地下)かつ高温・高圧・高腐食性(~500℃、~50MPa、PH~1.5)の過酷環境下における流量計測が極めて困難なためである。従って、その流量センシング法の基盤技術を構築することは、超臨界地熱発電実現への貢献が期待できる。
