Abstract

JAXAでは宇宙環境を利用した拡散係数測定のための実験技術の研究を進めており、温度勾配炉(GHF: Gradient Heating Furnace)を使用するための試料カートリッジとシアーセルを開発している。本年度は、GHFを用いた均熱加熱実験のための加熱パラメータおよび電気炉配置の最適化を行い、1,000度Cにおける均熱実験が可能であることを確認した。<br />The experimental techniques for the measurements of diffusion coefficient have been studied in JAXA toward the utilization of microgravity environment in ISS (International Space Station). The experimental cartridge for the Gradient Heating Furnace, GHF, was developed for the application of shear cell which is the advanced technique of diffusion experiments. The temperature profiles of GHF were measured for the diffusion experiments and the isothermal condition can be attained by the optimization of furnaces positions and temperatures.<br />資料番号: AA0063323001<br />レポート番号: JAXA-RR-06-015E
