Abstract
An improved information transfer mechanism is developed to couple fluid and granular modules for Incompressible Smoothed Particle Hydrodynamics modelling of sediment transport. The interaction force pair necessitates effective projection of information among parallel continuum based modules. The particle position in either module is susceptible to considerable variation due to their Lagrangian nature. An attempt has been made to minimize the effective thickness of the diffused interface between the fluid and granular particles. The proposed model reduces artificial drag force resulting from diffused computation of effective porosity. The revised framework outperforms in coarse resolution compared to its existing counterpart.
