Convection in a fully immersed granular slurry.

摘要: Using vertical vibrations, we have induced convection in a granular system completely immersed fluid inside cylindrical container. Convection is established single roll, which carries the material upward center and downward along side walls of We measure rise times tracer particles embedded medium at various depths central axis system. By fitting this data to an appropriate functional form, obtain information on depth dependence velocity. Significant differences are found frequency acceleration amplitude between wet otherwise identical dry systems. In addition, find that power-law form provides better fit our than logarithmic used
