Abstract

The objective of this project is to understand and predict correctly low Reynolds-number turbulent flows and turbulent dispersion in porous media. This is relevant to flow and dispersion through stored food produce such as grain and potatoes, hedgerows and crop canopies. Flows will be simulated using the lattice Boltzmann method and validated against experimental data to be obtained in laboratory-scale experiments. Macroscopic quantities like permittivity and diffusivity will then be determined and related to pore structure and flow characteristics. Key hypotheses to be tested include: a) Stagnant zones in the flow play a significant role in determining transport b) Rather than dispersing, heavy particles (e.g. droplets) tend to accumulate along selected paths. c) The sequence of transitions from laminar to fully turbulent flow is dependent of geometry.
