✦ Synopsis

Individual particle velocities have been measured by photographing the movement of tracer particles in a completely transparent bed of glass particles fluidised with dimethyl phthalate. The system is shown to exhibit certain important anisotropic features, but the distribution function for each of the velocitv comnonents is anoroximately Maxwellian. The overall circulation pattern in the bed has been established.

Values of axial mixing coefficients for glass spheres 0.9 cm dia. fluidised by dimethyl phthalate have been determined. The process has been shown to be predominantly of a diffusion type, with the convection pattern of the solids not exerting a significant influence. The results have been compared w
