Drum Centrifuge Study of the Transport of Leachates from Landfill Sites.
Abstract
This report gives the results of a feasibility study of drum centrifuge modelling of transport phenomena. A discussion of the modelling of transport processes in general is included, together with a description of the scaling of accelerated physical models and the verification of scaling assumptions. This is followed by a description of the laboratory and lg experiments to determine the physical properties of the model medium and pollutant used and to estimate the sorption, diffusion and dispersion coefficients required in the modelling of transport processes. Details are given of the construction of the two drum centrifuge models used, together with the results of the second centrifuge test. These results were obtained both in flight and from analysis of cores and from ultra-violet photography after the test. These are discussed in the context of the role of geotechnical centrifuge modelling in the verification of numerical models of porous media transport.
