Abstract

Magnetic Resonance Velocimetry (MRV) is a versatile technique for measuring three dimensional and three component velocity of a fluid flow using an magnetic resonance image machine. MRV was originally developed to visualize and analyze blood flows in vivo, but has recently been utilized to visualize complex engineering flows. For example, it has been utilized to improve the design of cooling passage for a high-temperature turbine blade systems or to study the flow distribution in fuel rod bundles of nuclear power system. MRV has many advantages over optics-based flow visualization techniques such as particle image velocimetry (PIV). Since MRV uses magnetic signals it can be applied to opaque and complicated flow system like internal cascade flow. In addition, it does not require tracer particles and requires a short experimental time. This seminar addresses the basics of MRV and shows the applications of MRV recently conducted in Multiscale Heat and Fluid Flow Laboratory in Hanyang University.

Biography

Simon Song is currently a visiting scholar in UC Merced and is a Professor of Dept. of Mechanical Convergence Engineering at Hanyang University, Seoul, South Korea. Before joining Hanyang in 2004, he earned his master and doctoral degree in Mechanical Engineering from Stanford University, and his bachelor’s degree from Hanyang University. His research centers on development of flow visualization technique for a variety of flows including patient-specific hemodynamic flows, complicated geometric flows such as porous media, and microscale flows. He is also interested in drag reduction using superhydrophobic surface. He is an associate member of The National Academic of Engineering of Korea since 2021, and director of both Center for Smart Hemo-Dynamic Index Research and UWV Long-term Operation Research Laboratories.
