Fluid
Mixing Processes - USA Meetings
The annual US Fluid Mixing Processes (FMP)
meeting was held in Philadelphia and attended by 16 companies representing
chemical, pharmaceutical, and homecare product manufacturing companies,
as well as mixing equipment suppliers and CFD vendors. Presentations
were made on recent work, with a range of topics covered, including
mixing of viscous non-Newtonian fluids, emulsification, three-phase
(gas-solid-liquid) mixing, and Computational Fluid Dynamics (CFD).
Plans for the further development of FMP's electronic Mixing Design
Guides were also discussed.
The event which
is now well established in the state-side calendar was also attended
by several invited observers who had the opportunity to discuss
their problems directly with the FMP consultants and their industrial
peers. The next event will be held in the UK near BHR Group's offices
in Cranfield, Bedfordshire on the 15th to 17th of September. The
next US meeting is scheduled for the 11th and 12th May, 2004, and
will again be held in Philadelphia. 6/6/2003

DTI
supports Process Intensification Workshops
Integrating Process Intensification technology with other technologies
such as simulation, measurement and control is the subject of a
series of workshops being hosted by BHRSolutions in the UK
this summer. The PI workshops aim to develop a technology roadmap
for the industrial uptake of PI based on an analysis of how PI is
currently being implemented by industry, and what it can't, but
needs to do, and the impact that the other technologies can have
in accelerating its commercialisation.
The workshops
are being supported by the UK's Department of Trade and Industry
(DTI) government department, through its Basic Technologies Initiative
programme, with expert advice for the workshops coming from the
universities of Newcastle, Strathclyde and UCL, and industrial organisations
Protensive and David Reay and Associates. Contact
us for more details, or see our pages on Process
Intensification technology, or our Conferences
and Training sections for details
of other BHR Group technical events. 19/5/2003

Decommissioning
Seminar
The DTI brought together a range of companies who offer skills and
services in the decommissioning of major plant under hazardous conditions.
The last seminar in the series was in Carlisle, on April 12th 2005
where BHR Group were exhibiting:
- System assessment
and design for slurries
and other rheologically complex materials based on over 25 years
experience
- DIAJET
abrasive waterjet cold cutting equipment which has been proven
for remote cutting of complex materials in highly hazardous zones
- Sealing
and containment
expertise from our world-leading sealing experts for engineers
designing bespoke machinery for decommissioning duties

Better
Processes for Mixing Nano-particles
We all have direct experience of the difficulty in mixing dry powders
such as packet sauces, medicines, etc, with liquids and the consequences
of getting it wrong - powders tend to float on the surface and/or
form lumps which are then difficult to breakdown. Well, image the
challenges the process industries will face when dealing with nano-particles.
BHR Group, with
its extensive Fluid
Mixing knowhow, is working in collaboration with leading industrial
and research organisations, to launch the PROFORM (Product Formulation)
research programme. PROFORM aims to deliver the next generation
of process design tools and methodologies to cope with products
formulated and manufactured from nano-particles.
The work will
involve experimental research, the development of numerical models
and best practices, and will result in new rules for designing and
operating process equipment. A long-term goal is to ensure industry-wide
access to the methods developed in the programme through their inclusion
in Computer-Aided Process Engineering (CAPE) tools. 1/7/2003

Engineering
Award to BHR Group CFD Specialist
The Institute of Mechanical Engineers' Fluid Machinery Group
recently awarded Dr Simon Leefe with the prestigious Donald Julius
Groen award for his paper on the Use of CFD in Design of a Shaft
Seal for High Performance Turbomachinery.
The paper, presented
by Dr Leefe, who runs BHR Solutions' Engineering Analysis
services, arose from a project to improve shaft seals for liquid
oxygen turbopumps used in the European Space Agency's satellite
launcher vehicles. Better shaft sealing permits smaller, lighter
pumps running at higher speeds and pressures. This saving translates
directly into payload capacity.
The paper focussed
on CFD as a design optimisation tool for this most challenging of
applications. The analysis involved prediction of hydrodynamic pressure
distribution, friction and turbulent leakage flow of a cryogenic
liquid through a channel of dimensions determined by a combination
of operating conditions, mechanical design and component thermal
and mechanical distortions. The novel aspects of the study were
the successful application of a commercial CFD code in the study
of turbulent lubrication, and the use of "design of experiments"
techniques to minimise computational effort in the optimisation
problem.
Dr Leefe and
his team of CFD specialists apply their knowhow across BHRSolutions'
activities to solve engineering problems in the Mechanical,
Process and Utilities
sectors. 19/5/2003

Waste
Water Mixing Consortium Launched
The fourth phase
of the WWM industrial
consortium was launched at meeting at BHR's offices where representatives
from , Thames Water, Yorkshire Water, United Utilities, Black &
Veatch Europe, Statiflo and Monsal agreed a research programme which
concentrates on the wastewater and sludge applications of:
- sludge conditioning
- sludge mixing
and blending
- dosing for
P removal
- anoxic zone
mixing.
The results
and deliverables from Phase 4 will enable participants to improve
mixer specification and selection, reduce chemical and powers costs,
reduce sludge volumes and improve process performance. The work
will also assist Water Companies in achieving compliance with their
treatment requirements and legislation. 19/5/2003
