Further understanding the small scale coherent structures which occur in high Reynolds number turbulence would be of enormous benefit. Therefore, the aim of the current project was to make well resolved three-dimensional ...

Under the threat of global warming it is vital to determine the impact that future changes in climate may have on the environment and to what extent any adverse effects can be mitigated. In this research an assessment was ...

Lean premixed combustion has potential for reducing emissions from combustion devices without compromising fuel efficiency, but it is prone to instabilities which presents design difficulties. From emissions point of view ...

This thesis considers the control of combustion oscillations, motivated by the susceptibility of lean premixed combustion to such oscillations, and the long and expensive development and commissioning times that this is ...

We describe here a library aimed at automating the solution of partial differential equations using the finite element method. By employing novel techniques for automated code generation, the library combines a high level ...

PrologPF is a parallelising compiler targeting a distributed system of general purpose workstations connected by a relatively low performance network. The source language extends standard Prolog with the integration of ...

The Cahn-Hilliard equation is of importance in materials science and a range of other fields. It represents a diffuse interface model for simulating the evolution of phase separation in solids and fluids, and is a nonlinear ...

Corporate business models are shifting away from product delivery paradigms to product-service paradigms, where ongoing through-life service support is preeminent. In the UK, a Grand Challenge project (www.kimproject.org) ...

Analysis of an interface stabilised finite element method for the scalar advection-diffusion-reaction equation is presented. The method inherits attractive properties of both continuous and discontinuous Galerkin methods, ...

This solver is in support of the paper 'Analysis of an interface stabilised finite element method: The advection-diffusion-reaction equation', by Garth N. Wells

Theoretical and experimental studies of particle deposition in turbulent pipe flow have been carried out for over forty years, but some of the most important transport mechanisms are still not well understood. The first ...

We examine aspects of the computation of finite element matrices and vectors which are made possible by automated code generation. Given a variational form in a syntax which resembles standard mathematical notation, the ...

This computer code is in support of the paper 'Automated Modelling of Evolving Discontinuities' by Mehdi Nikbakht and Garth N. Wells in the journal Algorithms.

The movies show the ignition process following a spark in a bluff-body stabilised methane non-premixed flame. The flow is described in: S.F. Ahmed, R. Balachandran, T. Marchione, E. Mastorakos, Spark ignition of turbulent ...

The movies have been taken at 4000 fps. The spark is placed at a distance z from the nozzle and at 5mm from the enclosure. The ignition unit delivers at 100Hz a spark lasting 8ms, followed by 2ms of no activity. The front ...

The movie (taken with a conventional video camera at 30fps) shows the various operation modes of the Cambridge Autoignition experiment, described in: C.N. Markides, E. Mastorakos, An experimental study of hydrogen ...

We examine aspects of the computation of finite element matrices and vectors which are made possible by automated code generation. Given a variational form in a syntax which resembles standard mathematical notation, the ...

The optical birefringence pattern obtained from lightly branched high density polyethyene (HDPE - produced by metallocene catalysis polymerisation) flowing in a cross-slot multi-pass rheometer cell. Experiment carried out ...

The video shows the flame motion following spark ignition in a turbulent methane jet. The flow conditions were: 30% air, 70% CH4, jet velocity 12.5m/s & 25m/s, framing rate 4200 fps, spark at r=0, z=40d (40 jet diameters; ...
