The project has been performed on ScandiNova Systems AB, a world
leader in the development and production of pulse generators. The
company has a number of water-cooled products in its range. In
order to make a cost-effective design of cooling systems, both the
company and their customers are interested in knowing the pressure
drop across the cooling systems, i.e. the force required to obtain
a given flow rate in the system.
In the various cooling systems, there are different types of
cooling plates which are manufactured by the company itself. The
goal of the project is to obtain pressure drop curves across these
cooling plates in the systems so a theoretical pressure drop can
be calculated early in the projects.
To determine the pressure drop across the cooling plates there
have been three different methods used in the work. The different
methods, which are the main elements of the project are:
theoretical calculations, CFD-analysis and practical measurements.
CFD analysis is performed by simulating the system in a specially
designed software for analysis of flows.
The results from theoretical calculations and practical
measurements support each other and as such the method is reliable
and valid to be used in continuous production and final
inspection. The results from the CFD-analysis differ from the
results from the other methods, which may be due to the factors
taken into account in the CFD-software.
