Outline of Final Research Achievements

In this study, time-resolved magnetic resonance imaging (MRI), a noninvasive medical diagnostic imaging technique, was evaluated as a non contact measurement tool for intuitively understanding fluid machinery. Simple pipe flows and channel flows are investigated to estimate this method’s applicability to fluid machines by the 2D Time-SLIP;spatial labeling inversion pulse (Time-SLIP) method, which can track a labeled water mass and visualize it using two-dimensional images.
Test results suggest that the time-SLIP method of tracking a labeled water mass is sufficiently accurate for use in simple flow paths such as piped flow and swirling flow under low Re number conditions. On the other hand, unclear images were obtained in fast flow with turbulence and it makes estimation of velocity distribution more difficult. Thus, it has been confirmed that MRI has highly possibility to become a powerful tool for machine design, although it still has many limitations.

Academic Significance and Societal Importance of the Research Achievements

近年,流動把握が可能なMRIが開発され,非侵襲的に流れの把握ができるようになった.しかしながら流動を観察できる流れ場の把握や整理は十分に行われていない.本研究で実施したTime-SLIP法による管内流などの基礎的な流れ場の時間分解撮像は,これまで直接観察することができなかった流路を過ぎる流れに対するMRIによる観察の適用性を調べたものであり,学術的意義を有する.またMRIは水や油などさまざまな流体を識別することが可能であり,医療分野から工業分野の広い分野にわたる流れの解析支援ツールとして活用できることを示したことに社会的意義を有する.
