Three-dimensional Modelling of Industrial Granular Flows

The Discrete Element Method (DEM) is attracting increasing interest for the simulation of industrial granular flows. While the majority of previous DEM modelling has considered two-dimensional flows, we present here a series of three-dimensional simulations for a number of important industrial applications. The charge motion in a 5 m diameter ball mill and in a Hicom nutating mill, discharge fr...

Modelling air flows around buildings in urban environment

In urban areas, main air flows from prevailing winds are strongly modified, depending on constructions’ morphology and urban microclimate’s effects. The meteorological data on the wind speed are often available from outside city centres whereas this wind speed is tough to assess in the urban canopy layer. The meteorological models which are developed from regional level to urban canopy layer le...

A Numerical Model for Three Dimensional Polydisperse Bubbly Flows around Surface Ships

A model for simulating three dimensional polydisperse two-fluid open bubbly flows is presented. The polydisperse model is based on an integro-differential equation for the bubble size distribution function. A multigroup approach is used to discretize the equations in groups of constant mass. The resulting system has four scalar equations (mass and momentum) for the liquid phase and for each gro...

Modelling Three-Dimensional Rotating Flows in Cylindrical-Shaped Vessels

This paper reports on a study concerned with the numerical simulation of dough kneading that arises in the food processing industry. The flows considered are in a complex domain setting. Two dough mixers running at various rotation speeds are studied; one with a single stirrer, the other with two stirrers. Stirrers are fixed on the lid of the vessel and the motion is driven by the rotation of t...

Direct Numerical Simulation of Separated Low-Reynolds Number Flows around an Eppler 387 Airfoil

Low Reynolds number aerodynamics is important for various applications including micro-aerial vehicles, sailplanes, leading edge control devices, high-altitude unmanned vehicles, wind turbines and propellers. These flows are generally characterized by the presence of laminar separation bubbles. These bubbles are generally unsteady and have a significant effect on the overall resulting aerodynam...
