Simulation technologies are becoming more and more important when it comes to development processes, process optimization, mechanical strength examination, accident analysis and lots of other technical questions. To deal with these application areas, the Computational Fluid Dynamics (CFD) is increasingly gaining importance for figuring out solutions for technical problems. The weyer group has been deploying the CFD technology for years in order to deal with a variety of ways of looking at a problem. This procedure has proven to be a very good alternative since the experimental research of complex fluid flows requires a highly sophisticated technique and is sometimes downright impossible to execute.

(pollutants, heat, etc.)
• Accident analysis (propagation of
pollutantsindifferentmedia,expansion
of blast waves after explosions, etc.)
• Fire simulation (dimensioning of smoke
and heat outlets), flue gas propagation,
etc.)
• Simulation of evacuation procedures
• Optimization of adsorption systems
• Design of process furnaces
Furthermore, the engineers of the weyer
group make use of a variety of analytical
models (EFFECTS, RiskCurve, etc.) in
order to deal with various safety related
questions like, e.g. accident analysis or
quantitative risk analysis (QRA).

The weyer group has been deploying the
CFD technology for years in order to deal
with a variety of ways of looking at a
problem. This procedure has proven to be
a very good alternative since the
experimental research of complex fluid
flows requires a highly sophisticated
technique and is sometimes downright
impossible to execute.
The experts of the weyer group have a rich
faculty of know-how and a high degree of
expertise at their command in order to
deploy this state-of-the-art simulation
technology. The professional application
of the numerical simulation has become
an indispensable instrument for the
acceleration of development processes,
for the optimization of procedures and
products and for the verification of safety
measurements.
It furthermore allows for a significant
reduction of development risks. Hence,
the CFD has become the standard tool
when it comes to finding ways of posing
fluidic questions and solving problems
related to mechanical strength properties.
Considering all these aspects, the weyer
group is in the position to support clients
from a great variety of lines of industry in
their processes to develop new products,
in their efforts to plan and optimize plants,
to execute accident analysis and to solve
problems related to mechanical strength.
The CFD-simulation is used in several
different application areas:
• Calculation of the line of flow,
the pressure decrease, the heat
transmission of gases and fluids.

nificant competitive edge towards your
competitors.
3 Quality improvement
The simulation allows for the detection of
weak points at prefabricated parts and ex-
isting components. Hence, points in need
of improvement like, e.g. turbulences in
components or dissolving processes inside
fluid flows can be detected. A correspond-
ing modification at the parts and compo-
nents can be executed immediately so that
their functioning will be optimized.
4 Gaining better insight
The simulations visualize, for example, se-
quences like velocity fields inside fluid
flows. They will put you in the position to
obtain a deeper insight into the decisive
parameters of your system. This is of par-
ticular importance when it comes to
complex processes which, for technical
measurement reasons, are often hardly ac-
cessible.

Benefits from simulations
À Saving of costs
À Saving in time
À Quality improvement
À Gaining better insight
À Secure system operation
1 Saving of costs
At the early stage of the component design
you will be able to display various designs
so that a preselection can be carried out.
By means of the simulation the advantages
among the possible alternatives will
become recognizable. The time and effort
for the construction of prototypes or the
execution of sophisticated experiments
can be significantly reduced and even be
cancelled respectively.
2 Saving in time
The simulations will already be carried out
during the development phase. The prop-
erties of your component can thus be ana-
lyzed in each stage of its development.
Herewith, the development time will be
shortened, since the modeling and simula-
tion, based on CAD-data, can be executed
faster than the repeated construction of
new models and prototypes. The product
cycles will continuously become shorter
and so, this gain in time saving for the

5 Secure system operation
By means of state-of-the-art simulation tech-
nologies you will be able to describe pre-
cisely the impacts of potential accidents.
These results enable you to develop corre-
sponding counter measures so that a secure
system operation and a proper procedural
process can be guaranteed. In doing so, it
doesn´t matter whether it is the dispersion
of toxic gases, a fire, explosion effects or
questions concerning structural dynamics:
We will provide you with the appropriate
solution for any of these problems.
Your benefits:
À Development of efficient optimization
facilities
À Innovative and economical solutions
À Elaboration of authoritative forecasts
À Feasibility checks of alternatives
without extensive time and effort
À Accident analysis
À Verification of a secure plant operation
