Particle transport, depostion, and resuspension in turbulent fluid flows

Cel



Research objectives and content
The principal objective of the proposed work is to develop and apply a probability density function (pdf) approach to the at transport of solid particles in bounded turbulent fluid flows involving both deposition and resuspension at the walls. The pdf approach permits detailed descriptions of particle-surface interactions, and also enables a set of transport equations for the particulate phase to be derived in a systematic manner. Thus the proposal will entail the development of various models for different types of boundary, the numerical solution of the pdf equation and the resultant continuum equations via either finite element volume or Boltzmann iattice gas methods, and a comparison of the results with experimental data. Emphasis will be placed on understanding and predicting the universal time behaviour find on elucidating differences in resuspension models.
Training content (objective, benefit and expected impact)
Models in use at JRC Ispra for particle resuspension will be incorporated into a pdf approach. Innovative numencal schemes will also be developed to solve the resultant pdf equation. Theoretical predictions will be compared with experimental data trom large- and small-scale experiments at JRC Ispra. This will lead to a general purpose code, describing the complete behaviour of particle transport for numerous types of boundary, which will be based on rigorous methods and validated against expenment. Links with industry / industrial relevance
Use will be made of the experimental facilities at JRC Ispra to obtain data with which to compare the theoretical results thus helping to validate the models used. The JRC work on particle deposition/resuspension (theoretical and experimental) has been partly funded by the Italian Energy Authaurity (ENEL) and by numerous research institutes [CIEMAT (Spain). Riso (Denmark)]. The calculation of particle deposition/resuspension is important in numerous industries, for example in the nuclear industry, in clean room technology and has environmental applications.
