Abstract
A theoretical description of the aggregation kernel homogeneity for fractal aggregates in the slip regime is developed. Experimental values of the kernel homogeneity were determined with dynamic light scattering measurements on titania and silica aerosols at pressures of 1/10 to one atmosphere. These experiments yielded aggregates with a fractal dimension of ca. 1.75 and aggregate radii to cover a range of Knudsen numbers of 0.04-3.8. Measurement of the fractal aggregate mobility radius as a function of time during aggregation gave the homogeneity. Agreement of theory and experiment is in general successful.
