Modeling on Effect of Particle Sediment on Fluid Flow and Heat Transfer of Solid–Fluid Suspension

A two-way coupling particle flux model is proposed for studying the multi-component solid–fluid suspension. The suspension mixture treated as a non-linear single-phase fluid and migration of solid particles modeled by equation. takes effects on transport suspension’s momentum internal energy into account. Two benchmark problems are calculated to study performance model, i.e., flow in sudden expansion straight channel between two rotating cylinders. It found that converges without numerical stability issue with commonly used PISO-SIMPLE transient solver, effect evident both velocity profile temperature distribution.
