چکیده انگلیسی
This work presents a validation study of new filtered Two Fluid Model closures for interphase momentum exchange and mesoscale solids stresses. Good quantitative comparisons to experimental data were achieved over a wide range of fluidization velocities. The new models also showed good grid independence behaviour compared to two benchmark models from literature. These encouraging results in realistic 3D flows were achieved even though the models were derived from 2D resolved simulations. Comparisons to a benchmark model derived from 3D simulations suggests that it may be more accurate to derive filtered models from resolved simulations conducted in a large 2D domain than from resolved simulations in a small 3D domain. Furthermore, the new model validated in this work could achieve good results in wall-dominated flows without the use of specialized wall corrections. Further work is therefore recommended to test these new filtered models in more flow situations and to further assess the ability of filtered models derived in 2D to predict real 3D flows.
