Multiphase Flow Visualization using a Benchtop MRI

Many multiphase flow experimental techniques utilize noninvasive methods like high-speed optical imaging, laser-based diagnostics, and/or X-ray techniques. However, high-speed imaging and laser-based diagnostics cannot see through opaque multiphase flows, and X-rays have challenges with respect to safety and resolution. Magnetic Resonance Imaging (MRI) has been used to visualize multiphase flows, but most MRI machines are often very expensive and/or have limited access. This poster will outline a benchtop MRI that can be constructed with off-the-self items and 3D printed housing. Although much smaller in size compared to a medical MRI machine, it is still capable of multiphase flow visualization. Both gas-liquid (bubble column) and gas-solid (fluidized bed) flows will be visualized using this benchtop MRI.
