TITLE:
The Brookfield Powder Flowability Tester.

AUTHORS:
Bradley MAS.

JOURNAL:
Product not paper.

DESCRIPTION:
Describing the detailed research in the project (funded by DEFRA and international industry) to develop an industry-accessible instrument to measure flow behaviour of powders, for formulation, quality control and equipment design to avoid powder flow problems which cost industry large sums of money. Commercialised by Brookfield Viscometers (US multinational) and sold in around 30 countries so far (200+ units since January 2010). Product was Runner-up in Times Higher Education Awards, IChemE Innovation award, and was in US “Top 100 Innovations” for 2011. Over 40 follow-on projects funded by industry to use this technique for research into properties of their products and/or plant design.

TITLE:
Scale-up and design of a continuous microwave treatment system for the processing of oil-contaminated drill cuttings.

AUTHORS:
Robinson, J.P., Kingman, S.W., Snape, C.E., Bradshaw, S.M., Bradley, M.S.A., Shang, H. and Barranco, R.

JOURNAL:
Chemical Engineering Research and Design, 88 (2). pp. 146-154. ISSN 0263-8762, 2010.

DESCRIPTION:
The result of DEFRA and industry funded work to develop a novel method of treating cuttings from drilling of oil exploration wells, to prevent discharge to sea. It described the new technique and how it can be applied in practice including the key practical considerations for making it work safely on an oil drilling platform. The design has been the subject of a patent and is under consideration for commercialisation.

TITLE:
Development of a State of the Art Technique for Characterising Powder for Pneumatic Conveying Properties, and Design of Conveying Pipelines.

AUTHORS:
MSA Bradley, RJ Farnish, T Deng,.

JOURNAL:
??????.

DESCRIPTION:
Describing research that delivered the best method yet devised for measuring the behaviour of powders and bulk materials in conveying pipelines, and use of this for more accurate design of pipelines in industry. The software design tool produced from it has been embedded by two leading companies supplying conveying systems, Alstom Power (multinational) and Portasilo (UK based/global exports); around 20 further companies have funded follow-on projects at The Wolfson Centre using the technique for research into their products and/or plant design. Around 80 engineers from 60 companies have paid to attend a 2-day course based on this, since 2008.

TITLE:
A Novel Approach to Velocity Measurement of Pneumatically Conveyed Particles Around 90o Bends using Electrostatic Charge Sensors.

AUTHORS:
Gorman T, Bradley MSA,.

JOURNAL:
?????????.

DESCRIPTION:
This paper presents a new way of studying the loss of energy due to bends in pneumatic conveyors, which is the primary cause of energy loss in such systems which consume many megawatts of electricity in the process industries and causes many millions of pounds worth of damage to products conveyed in industry in this way. The novel method has already led to two follow-on projects, one PhD project sponsored by a large German processing company and another PhD project sponsored by Nigerian government, to use this technique to further investigate and understand the degradation of particles in handling with a view to developing a model for particle degradation that can predict it from small-scale tests prior to a plant being built.
