CFD Modeling of Mixing Facilities

CFD Simulation for Mechanical Mixing Systems •In the past 20 years, CFD has emerged as an attractive choice for simulating systems that employ mechanical mixing. •This is due to two elements in physical modeling that can drive up its cost. •Scaling laws are difficult to satisfy with mechanical mixers.

The rotation is applied on the outer boundary (R_outer) and should cause the flow outside to circle around it. The force must then be transmitted through the structure to the R_inner and the inside fluid should also get the same angular ...

A parallel computation method has been proposed for the mixing and segregation of granular mixture included in gas and liquid flows. In this method, a three-dimensional (3D) computational volume is decomposed into multiple sub-blocks and their geometries are represented by 3D body-fitted coordinates. The fluid-particle interactions are treated by two types of models: a two-way model for liquid ...
