Aggregation model

Report on aggregation modelDust and sand lifted or suspended after the splash of a wind blown particle encounter other particles before the impact again or are resuspended for long time Especially dust grows to larger aggregates by hitandstick collisions The growht process is unknownThe project will use the experimental results to work out a model that describes the time evolution of particle properties depending on the environment including aggregate size aggregate morphology porosity or fractal dimension and drag coefficients
