| Abstract | To account for the sub-grid heterogeneity of bubbling gas-solid flows in the multi-phase particle-in-cell (MP-PIC) method, a bubble-based EMMS/DP drag model is proposed in this work by taking into account the particle/parcel position information. The local, inter-parcel porosity is calculated by using the method of smoothed particle hydrodynamics (SPH), while the intra-parcel porosity is closed by using the Energy Minimization Multi-scale (EMMS) model. The local velocities of gas phase and different solid parcels are determined by using the constraint of pressure drop balance between phases as in the EMMS/bubbling model. The drag force acting on each parcel is then determined with the sub-grid information of velocities and porosities. Two cases of bubbling fluidized bed are simulated to validate this drag model. And the results show good agreement with experimental data. (C) 2020 Elsevier B.V. All rights reserved. |
