Career Summary

Biography

My primary consulting expertise is in the use of numerical modelling to solve industrial problems. Initially, this was in the field of conveyor belt transfer chutes, however more recently has expanded into more unique and challenging areas such as quaking bins, feeders, vibrating screens and the modelling of particle breakage. Since joining TUNRA Bulk Solids in 2007, I have been involved in over 170 industrial projects, including both the conceptual design stage as well as trouble shooting existing designs, in Australia and Internationally, and involving a wide range of products. Typically, these projects require the use of both a traditional continuum mechanics approach and as well as the Discrete Element Method (DEM). These projects have covered many industries, with the main ones being coal and iron ore. 

My current research interests have been in the area of transfer chutes, specifically in the area of passive dust control techniques and calibration of parameters for Discrete Element Modelling (DEM). The research on dust control has involved the use of both Computational Fluid Dynamics (CFD) and DEM and has on focussed on reducing dust generation in transfer chutes through passive means (no external energy sources). The research on the calibration of DEM parameters is ongoing and is vital in the successful application of this modelling technique to solve industrial problems. 

My research focus throughout postgraduate research was on the topic of permeability of packed beds and included developing and writing my own packing algorithms to simulate packed beds of spheres as well as fibrous materials. This modelling background served as an excellent platform to move into the field of DEM and CFD. 

Through involvement with the University of Newcastle, I have been involved in the supervision of Final Year Project Students, Masters Students and PhD Students. Since my time as an Postgraduate student at the University of Newcastle, I have also been involved in lecturing and tutoring for a range of undergraduate courses including Introduction to Procedural Programming (Fortran, Matlab), Introduction to Engineering Mechanics (Dynamics), Engineering Computations 2, Engineering Mechanics and Mechanics of Bulk Solids and Particulates. 

Through my role with TUNRA Bulk Solids, I have also been involved in the delivery of short courses to Industry. Since 2009, I have assisted with the delivery of approximately 20 short courses that ranged in length from 1 - 5 days.

Dust emission is one of the main problems in the operation of transfer chutes. The design of the transfer chute heavily influences any potential dust generation. Although this influence is well known, much more attention is given to active dust suppression via water spray systems, the exhaustion of the dust polluted air or the use of electrostatic filters rather than the design optimization of the transfer chute. Due to the very specific design of the transfer chutes, sophisticated simulation methods such as Computational Fluid Dynamic (CFD) and Discrete Element Method (DEM) are necessary to predict the material and air flow in such plants. This paper shows how both simulation methods can be used for predicting the material and air flow through a transfer chute. Two approaches will be presented: Eulerian multiphase CFD simulation and directly coupled DEM-CFD simulations. Both approaches will be used for the simulation of the air / material flow in a laboratory-scale transfer chute with different design characteristics. This allows not only the comparison of the different simulation approaches but also a comparison with experimental data. The paper highlights the boundary conditions and entries for the different simulation approaches as well as discusses the advantage and disadvantages of each method.

This article presents the outcomes from a series of physical experiments to measure the air entrainment rates encountered within a stream of freefalling particles. The experimental work presented spans a range of particle parameters and hopper geometries. From these results a new theory for the prediction of air entrainment is developed and presented. This new method was developed specifically to facilitate a better understanding in the area of fugitive dust control associated with material handling systems, which are driven by the air entrainment during freefalling. From the work presented in this article, a better prediction capability of freefalling bulk materials in either constrained, or unconstrained systems, will allow for the optimization of either passive or active dust control strategies. This article presents several distinct sections that detail the experimental work used to determine the freefall stream parameters that were conducted to allow the development of the entrainment equations. © 2013 Taylor & Francis Group, LLC.

Train load-out bins are generally large structures that employ flood loading chutes to rapidly load material into wagons. It is often important when designing these structures to consider the dynamic loads associated with the rapid unloading of the material as these loads can often cause vibrations. Typically, calculations for the dynamic loads are based on traditional continuum calculations coupled with site data, as the unloading rate depends on factors such as gate opening time, the corresponding outlet size, train speed, and material properties. The continuum approach has been previously illustrated in the past with a case study [1] . This paper will present results using the Discrete Element Method (DEM) on the same case study and will compare results in terms of instantaneous flow rates, as well as dynamic forces and accelerations of the flowing bulk solid during discharge.

A co-operation among Universities of Newcastle, Australia, and Magdeburg, and Germany, is established to develop and apply the new analysis methods such as Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD), for prediction of diffuse dust emission from dust exhaustion plants. The combined analysis of DEM and CFD includes two CFD simulations, the air flow in the bulk material stream and the air flow around the bulk material stream. The boundary conditions for the calculation of the air flow in the enclosure are set. The results of CFD simulations show that the exhausted air does not come from the impact zone of the material stream on the receiving belt conveyor, but from the opening above the incoming conveyor belt. It is also found that the air with the highest dust content can be found on top of the receiving conveyor.

The paper presents a theory, combined with design equations, to compute the loads on structural elements, in particular those of trestle legs of tubular construction supporting load-out belt conveyors, where the trestle legs are substantially buried in gravity reclaim stockpiles. The stress conditions, both active and passive, that arise during filling and reclaim are examined taking into account the position of the trestle supports with respect to the load out conveyor discharge during filling, and reclaim hoppers during draw-down. The theory examines the various loading conditions due to the stored bulk solids focusing on the determination of the lateral or bending load distribution on the trestle support legs. The compressive, in-plane shear traction loads which may influence the buckling effect in the buried legs are also examined.

Open front inclined apron feeders are used widely in the mining industry to transfer run-of-mine ore into primary crushers. In the design of these apron feeders it is necessary to understand the mechanics of the feeding action at the hopper/feeder interface to allow for accurate determination of the power requirements of the drive unit. The focus of this particular study is to present current theory that can be used for the prediction of the shear force at the feeder belt interface and the corresponding power required for the feeder. A continuum theory approach is presented in conjunction with Discrete Element Modelling (DEM), with both of these results then compared to experimental results from the laboratory.

A technique to simulate airflow around transfer chutes that involves linking Discrete Element Method (DEM) commercial package Rocky and Computational Fluid Dynamics (CFD) commercial package ANSYS Fluent is proposed. The flow of particles is first calculated in the DEM domain; after that continuum parameters of this flow (porosity, mean particle size and cell-averaged particles velocities) are calculated and used as input into ANSYS Fluent CFD package for the solution of the airflow. This solution is carried out using a single-phase moving porosity approach with User Defined Functions (UDF) for porosity and particle-based momentum terms in Fluent based on phenomenological interaction laws. The comparison against experimental results for a laboratory-scale transfer chute demonstrates a good match between experimental and computational data. Several turbulence models and particle-gas interaction laws have been tested and it was concluded that for this problem the choice of interaction laws and turbulence models does not affect the results of the simulation to any significant degree.

The further advancement of silo quaking research through the application of state-of-the-art Discrete Element Modelling$18,216

Silo Quaking is a significant dynamic problem that occurs in all forms of industry involving the handling of bulk granular materials. In recent times, the severity and frequency of silo quaking problems have increased dramatically along with the scale of many Australian industries.

This pilot project aims to build momentum towards securing external funding in this area through developing Discrete Element contact models specifically tailored towards investigating silo quaking mechanisms.

Using this numerical analysis tool we will seek to understand a range of complex phenomena observed in prior experimental work.  This will allow us to move towards a full understanding of the phenomenon and the ability to predict the occurrence and severity of silo quaking in industrial situations
