摘要：
Brazil-nut Effect (BNE) experiment in (real) two-dimension is conducted. Container, bed particles, and intruder are made from the same material, i.e. 2 mm thickness acrylic plate. Dimensionless acceleration F and vibration frequency f are in the range of 2-4 and 13-17 Hz, respectively. It is observed that rise time T-rise decreases with the increase of F similar to reported by others, but there is a range of f and Gamma, where T-rise increases with the increase of Gamma due to occurrence of Leidenfrost effect, which reduces convection flow of granular particles.
