High-viscosity mixing with triple impellers

Plastic and rubber materials are used in many industrial products for their excellent molding and processing properties. These materials are highly viscous, and if air is sucked into them during the manufacturing process, it is difficult to release the air, and if they harden in this state, the original properties of the material may be lost.

For this reason, air is removed by agitation, or in other words, defoaming is performed. In this simulation, the stirring of a high-viscosity liquid with three agitating blades that are rotating in opposite directions is evaluated. The particle method is stable for such a high-viscosity flow and requires only a small number of calculations.​
