Selected Projects

Simulation of a Circulating Fluidized Bed

Circulating fluidized beds are widely used in chemical, process and metallurgical industry. The simulation of a fluidized bed can help to improve heat and mass transfer reaction rate, optimize residence time and product uniformity.

Simulation of a Blast Furnace


CFD-DEM simulations can help to improve blast furnace operational parameters such as the impact of charging recipe on the uniformity of solid fraction, the impact of hot blast mass-flow rate and velocity on race way size and shape.

Simulation of a Ball Mill


Ball mills are widely used in the minerals and mining industry. CFD-DEM simulations can help to improve their performance and reduce down-time and maintenance.

Optimization of a Mower Deck

The goal of this case study with Aspherix and CFDEMcoupling was the optimization of a mower deck with respect to ths cut quality. Since the design contains blades with intersection trajectories it was not possible to use sliding meshes. A new IB approach designed for mower deck applications was used.

Simulation of a Rotating Drum

This application case combines numerous functionalities. Particles are wetted by a spray and heated by convection. The heating of the particles causes them to dry while powder leads to a coating of the particles. At collision, the coating of the particles undergoes attrition and the attrition is dispersed in the gas as dust.

Optimization of a Transfer Chute

The simulation above shows the dust emission in a transfer chute system, in both a simple and an improved geometry. While in the simple geometry, dust can escape the transfer chute and can pose a possible health and explosion hazard, the dust is kept within the transfer chute in the improved geometry.
