EXAMPLE
PROJECTS: CONFIDENTIALITY!
Because work for clients is carried out under strict conditions of confidentiality and in
order to protect the pursuit of IPR by clients, only a flavour of projects can be given here
|
HIGH FLOW RATE FINE WATER SPRAYS
This project involved
working with a client to propose, construct and test a novel air assist atomizer capable of atomizing around one litre/min
water to 15 microns mass median diameter, but with severe restrictions on air pressure and flow rate. A satisfactory device
was developed with a performance that far outstripped available commercial atomizers.

DESIGN OF SPRAY TEST APPARATUS
In this project
the detailed design was developed for a company, for a spray test apparatus for measuring drop size and patternation for sprays
from a wide range of atomizer types. The apparatus contained liquid pumping, traversing and spray collection facilities and
utilised PDA, Malvern and other measurement techniques. The apparatus was constructed and is in routine use.

REDUCING OR REMOVING VOC IN AEROSOLS
Projects have
been carried out for several companies on different aspects and approaches to producing household aerosol sprays but with
minimum, or no, VOC content in propellant or contents. A common feature has been technology transfer from other spray fields,
to improve the efficiency, and thus reduce the energy requirements, of the insert geometry. Several patents have arisen from
these projects, with devices now being launched on the market.

FLAMMABILITY OF SPRAYS OR AEROSOLS
Three major
safety oriented projects have been carried out for major concerns, covering (a) the inert gas dilution requirements for avoiding
flame propagation in aerosols of fuel, and (b) two projects on the ignitability of accidental sprays of hydraulic fluids.
One of the latter projects led to the development of a new EU standard testing specification. The projects involved the design
and construction of test apparatus and the carrying out of experiments in close cooperation with the sponsors.
|
FOOD COATING
Contributions have been made to several
projects aimed at optimising particular coating procedures in the food industry. Background experience from several spraying
fields led to achieving improved evenness of coating and with minimal overspray. An important feature was the choice of optimum
spraying atomizers, with experiments to ensure this optimisation.

|
IMPROVED
AND NOVEL PAINT APPLICATION SYSTEMS Contributions to industrial projects
have been made for the devlopment of new systems aimed at gaining advantages in fines/drift reduction, low power, convenience
and flexibility. These contributions include particiapation in design and
development meetings, computational fluid dynamics, design exercises and measurement and data analysis
