The effects of heterogeneous, meso-scale structures within a computational cell are critical to computational fluid dynamics (CFD) for particle-fluid two-phase and multiphase flows. In recent years, we have witnessed a blossom of meso-scale modeling, among which, the energy-minimization multi-scale (EMMS) modeling of drag, heat and mass transfer and reactions has found successful applications in various areas. However, difficulties have been occasionally encountered by users. WCPT will organize a half-day course and a half-day workshop on EMMS modelling and exchange experiences to help users begin their coding with EMMS and address the difficulties occasionally encountered for users.
