Predicting Liner Wear in a SAG Mill using Rocky DEM coupled with ANSYS CFD

LEAP will be in Melbourne at the 2nd Int'l Symposium on Computational Particle Technology to showcase exciting new modelling work that has been completed recently using Rocky DEM and ANSYS CFD to predict liner wear in a semi-autonomous grinding (SAG) mill, using ANSYS CFD to model the effects of slurry flow within the mill on liner wear and particle breakage.

Using CFD to enhance your mixing process and drive down costs

Mixing processes are critical to a wide range of industrial applications across the the paint, food, pharmaceutical, minerals and water treatment industries. CFD is becoming fundamental to the successful operation of mixing processes including clarification, cell culture growth, fermentation, polymerization and blending.

Tips & Tricks: How to interpret results for multiphase & porous domains using true velocity and superficial velocity

A commonly asked question is: What is Superficial Velocity and when do I use it?   If a fluid flows through a region that is occupied by either fixed structures (a porous region, pipe rack, catalyst bed, etc...), or shares the channel with other fluids (e.g. gas-liquid flow), there are two ways to describe the fluid...

(Part 2) 10 Useful Tips on selecting the most appropriate multiphase flow CFD models

As we discussed in our previous post, the first step when  tackling a multiphase CFD problem is to identify the key characteristics of your physical system.  Once you've done this (using our checklist if you are still new to multiphase CFD), you can begin to make informed decisions on what multiphase modelling approaches to use....

In advance of his visit to Australia in December, LEAP Australia is pleased to announce a webinar to be conducted by Dr. Markus Braun on Wednesday November 14th at 4pm AEDT (Syd/Mel daylight savings time).  This webinar will provide an overview of multiphase flow modelling techniques and discuss recent advancements that impact the use of...

10 questions to ask yourself when tackling your first (or a new) Multiphase CFD project

By virtue of the many physical processes we are often attempting to simulate in a virtual environment, CFD can be a complex beast.  To accurately account for all real-world behaviour, the CFD engineer must consider the applicability of a large number of physical effects, including complex turbulence, compressibility, various modes of heat transfer and, last...
