Magnetic Resonance Velocimetry (MRV) is an experimental method to obtain velocity fields in fluid mechanics. MRV is based on the phenomenon of nuclear magnetic resonance and adapts a medical magnetic resonance imaging system for the analysis of technical flows. The velocities are usually obtained by phase contrast tomography techniques. This means velocities are calculated from phase differences in the image data that has been produced using special gradient techniques. MRV can be applied using common medical MRI scanners. The term Magnetic Resonance Velocimetry became current due to the increasing use of MR technology for the measurement of technical flows in engineering. ==Applications== In engineering MRV can be applied to the following areas: *Analysis of technical flows in complex geometries (separation, recirculation zones) *Validation of numerical simulations in computational fluid dynamics using 3D velocity fields *Iterative design of complex inner flow channels (combined with rapid prototyping) *Measurement of concentration distributions in mixing processes *Analysis of flow through porous media *Interaction of immiscible fluids 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Magnetic Resonance Velocimetry」の詳細全文を読む スポンサード リンク
