application of hybrid cells in series model in the pollution transport through layered material

The present paper aims at investigating the applicability of hybrid cells in the series model for pollution transport inside the layered porous media. for this purpose, four layers of rock material have fallen inside the experimental flume, with eight sensors installed longitudinally inside the media to obtain experimental btcs. in order to measure time parameters of the model, named λ,t1,and t1, two different methods of lscf and mm have been examined. the model's sensitivity as well as its temporal equations with different parameters have been assessed. finally, results show that at the fixed time step, the model is more sensitive to λ parameter (advection zone time parameter) rather than residential time parameters, to which the moment relations are more sensitive. a detailed computation of the related transport parameters has been operated and the peclet number, crossing velocity, dispersion coefficient, time to the max, and maximum concentration have been calculated. eventually, the model's applicability for large-scale porous media has been proven with only one unit of the cells.
