CFD software saves wasteful excess in
plant construction!
Due to many processes running in parallel,
nIs and its CFD concept are in high demand
as a partner, not only in the nuclear
sector, but also in conventional plant construction.
A current project revolves
around the calculation of the optimal hole
diameter for a gas distributor plate which
is used in a new electrostatic filter in an
industrial facility belonging to eVonIK.
As the customer has no empirical data or
values for the corresponding work range
of the gas distributor plate, and rough
estimates would have led to significant
uncertainties in both designs, the flow
patterns through the gas distributor plate
were calculated using CFD, and the interaction
with other plant components (such
as a compressor) was optimized. Without
the prompt and competent assistance of
nIs, the customer would not have saved the
considerable expense of complex testing.
Before the work was even completed,
the customer was so satisfied that they
requested a further quotation for a subsequent
project. this new project is likewise
concerned with the question of
optimizing the flow control in a large
electro static filter.
Further inquiries from the field of plant
construction illustrate the large scope of
application for CFD – e.g. optimizing the
flow mechanics of industrial filters, condensers
and heat exchangers, all the way
to the mixing processes of various substances
in boilers (liquid-solid) – or even
the spread of hazardous materials on industrial
premises.
nIs has already used CFD successfully for
calculating complex experimental fire tests
for hazardous material containers. the
knowledge gained here was used in the
development of new design approaches,
in order to develop an optimized cask.
Further internal projects are concerned
with calculating the spread of hydrogen
in buildings, and investigating a passive
cooling system for fuel pools. these
processes include detailed consideration
of various plant com ponents such as heat
Advantages of CFD
• Shorter development times,
and hence
• Cost savings
• Gain of knowledge, and hence
insight into the future potential of
the device
• Insight into processes for which
measurements cannot be performed
exchangers, natural circulation in piping,
and natural draught cooling towers.
nIs is currently opening up new paths and
applications, by transferring the benefits
of CFD to indoor server cooling systems,
and efficient air-flow systems in buildings
and cleanrooms. Here, too, we can see
the advantages of performing computer
simulation in advance of the real tests,
saving the users money, uncertainty, and
scheduling delays!
