Computational fluid dynamics (CFD) is an important tool for the simulation of the
cardiovascular function and dysfunction. Due to the complexity of the anatomy, the …

Biomass pyrolysis holds promise for both economic value and environmental benefits, while
rotary reactors offer advantages in material handling and heat transfer. Efficient pyrolysis …

CFD-DEM is used to simulate solid–fluid systems. DEM models the motion of discrete
particles while CFD models the dynamics of the fluid phase. Coupling both necessitates the …

The sharp interface immersed boundary method (IBM) is a powerful tool to simulate the flow
around moving objects. This paper extends this method to simulate the motion of particles …

In this work, we assess the accuracy of the unresolved CFD-DEM method by confronting
simulated and experimental results of a pilot-scale cylindrical liquid–solid fluidized bed. We …

The interaction force between fluid and particles in particulate flows is highly dependent on
the rheology of fluid. In some engineering applications, like mineral processing, the …

Experiments for the validation of unresolved CFD-DEM software for solid–liquid flows are
often expensive, time consuming and generally provide little insight into the local particles …

Approximately 75% of the raw material and 50% of the products in the chemical industry are
granular materials. The discrete element method (DEM) provides detailed insights of …

Adaptive Cartesian mesh approaches have proven useful for multi-scale applications where
particular features can be finely resolved within a large solution domain. Traditional patch …

The sharp-interface immersed boundary method is a strategy to impose boundary conditions
on complex geometries while simplifying the meshing process. This method can offer a high …
