项目摘要

東京工業大学に設置されている「クローズドループMHD発電実験装置」は,超音速ディスク形MHD発電機による長時間連続発電実証を目的とした世界に類を見ない実験装置であり,クローズドサイクルMHD発電の実用化に向けて重要な役割を担う。このMHD発電機の性能は発電機内のプラズマ電磁流体の挙動に完全に依存し,基礎物理現象や発電特性の解明,高性能化への指針を見極めるためには,その挙動を正確に把握することが必要不可欠である。本研究(平成18年10月から19年9月までの1年間)では,平成18年度から19年度にかけて行われた定格高温ガス循環試験ならびに発電実験において,電磁流体諸量および電気的諸量を計測するとともに,それらの数値計算結果との比較検討から,現象解明を試み,更なる高性能化を図るための指針を探ることを目的とした。平成18年度にまず発電流路内の高温高速気体流れの把握に焦点を絞り,特に数値計算による検討を進め,平成19年度は,定格高温ガス循環試験ならびに発電実験において,発電流路内熱流体計測を行うとともに,数値計算結果と比較検討を行い,本数値シミュレーションにより実際の流体現象が把握可能であることを示した。特に,従来の評価では見出し得なかった発電流路下流での境界層の剥離,大きな渦構造の発生とそれに起因する熱損失の増大を定量的に評価できた。発電実験では,数値計算結果が示すほどの性能が得られてないが,その向上に関する指針を明らかにすることができた。本クローズドルーブ連続発電実験装置を用いた発電実験が,今なお発展途上にあるので,実験結果と数値計算結果を完全に比較検討するには至っていないが,MHD発電機内の電磁流体挙動と高性能化に関する貴重な指針を得ることができ,本研究は研究期間を通して計画通りに遂行され,研究目的を達成することができたと自己評価している。

The Beijing University of Technology is equipped with the equipment for the safety of MHD aircrafts. The supersonic aircrafts are used for long periods of time. The purpose of the equipment is to meet the requirements of the world. The equipment is installed, and the equipment is used. The equipment is responsible for the use of MHD equipment for critical service. In the MHD electronic equipment performance monitoring machine, the electromagnetohydrodynamic performance is completely dependent, the characteristics of the basic physical simulation are clearly understood, and the high-performance performance monitoring is very active. It is correct to make sure that it is necessary to ensure that it is necessary. In this study (during the period from October 18 to September 19 in Pingcheng), in Pingcheng in 18 and 19, in the year 18 and 19, the high temperature temperature cycle was fixed in accordance with the temperature temperature, the volume of the magnetomagnetic fluid, the quantity of electricity, the temperature of the electricity, the calculation of the temperature, the results of the calculation, the results of the calculation, and the results of the calculation were compared. The purpose of this study is to explore the purpose of high performance. In Pingcheng, the high-temperature and high-speed flow in the middle of the year 18 has a good grasp of the focus of the flow, and the calculation of the temperature has improved, and the year 19 has been completed. Stop the high-temperature temperature in order to improve the temperature in the flow path, and the calculation results are better than those in the flow path. In this number, you may have a good understanding of the possibility that you may show that you have a good understanding of the fluid. In particular, you need to know that there is a problem that there is a problem in the flow of water, and that the whole system is responsible for the cause of the disease, which is the cause of the disease. The results of the calculation show that the performance of the computer is good, and the results of the calculation show that the performance of the system is not good enough. This equipment is used in this equipment. Today, the equipment is running on the exhibition. The results are calculated. The results are completely compared to those in the MHD machine. The performance index of the device is very high. During the study period, the computer simulation was completed. The purpose of the study is to make sure that you don't know what to do.
