Residence time of particles in a tubular suspension flow was found normally distributed when particulate radial migration caused by gravitational force was eliminated. The gravitational radial migration was eliminated by configuring the test tubes vertically. Initial conditions including radial position and velocities of the test particle had no effect on the RTDs. Among the five dimensionless groups affecting particle RTDs, suspension Reynolds number varied from 6300 to 26000 and particle volumetric fraction varied from single particles to > 20%. Empirical correlations were established for mean and standard deviation of normally distributed RTDs with respect to suspension Reynolds number and particle volumetric fraction.
