Abstract: Abstract We investigate the faster is slower (FIS) effect for a granular flow system which consist of a quasi two-dimensional hopper placed on a vibrating inclined plane. Increasing the angle of the plane (θ) is similar to increasing the driving force in the social force model. We measured the distribution of the time intervals between two successive particles (dt) and found that for narrow exits (3 particle diameter) it displays a power-law tail with a negative exponent α, were | α |
