MRI (magnetic resonance imaging) measurement was performed for a horizontally vibrated granular bed of binary mixtures in a liquid. Larger particles tended to rise through the central region. The size ratio of larger to smaller particles affected the segregation phenomena. The experimental results were compared with results of a DEM simulation. The calculated results agreed qualitatively well with the experimental results.
