Measurement and modelling of powder flow in flexible containers |
Prof. Jin Ooi
|
The research focuses on understanding cohesive powder flow in flexible bulk solid containers (buggies and bulk bags) with a view to develop a design methodology for ensuring reliable discharge from these containers. The project involves experimental powder flowability characterisation, finite element analysis of the stresses in flexible containers and pilot scale experiments to study the powder flow field and validate the new design methodology for reliable discharge.

Investigation of particle breakage of dry granular materials using x-ray computed tomography and the DEM |
Prof. Jin Ooi
|
When a load is applied to an assembly of particles and particle breakage occurs, the macroscopic behaviour of the assembly is greatly affected by changes in the micro-scale caused by breakage. In this project particle breakage is studied in 3D using x-ray tomography and simulating the process with the DEM.

Intelligent Egress: Real time modelling based upon sensor data to steer evacuation in case of fire |
Dr Stephen Welch
|
Intelligent egress is a novel approach to enhancing evacuations from fire emergencies. It combines sensor-linked simulations and route-planning tools to provide real-time information to occupants on efficient egress. The specific issues associated with disabilities and mobility impairment are addressed. Mechanisms to provide “way finding” information to relevant end users are being studied. Detailed guidance and recommendations on use of such systems will be developed.

IFPRI Grindability Project: modelling, measurement and mill fingerprinting |
Prof. Jin Ooi
|
This project aims to develop a robust methodology to characterise the grindability of particulate products in milling operations which will in turn provide a step-change in mill fingerprinting and optimisation. This involves developing a “grindability test” to measure the comminution characteristics of the particulates which, when coupled with the computational modelling work to characterise the milling function, will evaluate the milling performance measures including energy utilisation, breakage kernels for scale-up modelling such as population balance model of the mill.

High Performance Computing Support for United Kingdom Consortium on Turbulent Reacting Flows (UKCTRF) |
Dr Stephen Welch
|
The proposed UK Consortium on Turbulent Reacting Flows will perform high-fidelity computational simulations (i.e. Reynolds Averaged Navier-Stokes simulations (RANS), Large Eddy Simulation (LES) and Direct Numerical Simulations (DNS)) by utilising national High Performance Computing (HPC) resources to address the challenges related to energy through the fundamental physical understanding and modelling of turbulent reacting flows. Engineering applications range from the formulation of reliable fire-safety measures to the design of energy-efficient and environmentally-friendly internal combustion engines and gas turbines.
