Kruger is devoted to the
development of fan designs and application oriented
work in the areas of fan testing
and flow profile mapping. All research and code development
are organized by Kruger Research Team.
The basis for the application-oriented work is the development
of theoretical models, numerical algorithms and computational
tools. Current program developments are done in-house,
and in cooperation with customers and suppliers.
Computational Fluid Dynamics
The Computational Fluids Dynamics (CFD) Team is a part of the R&D Department at Kruger.
The CFD work in Kruger is mainly devoted to the development
of new fan product series. Analysis of flow problems
has been done with a range of methods including Navier-Stokes
computations. The group is also involved in the design
of improved aerodynamic blade shapes for future product
series. The work directed towards fan design is focused
on the operational efficiency of the fan and air flow
profile mapping. Current topics of study are
Fan blade optimisation
Experimental results verification and support
Air jet simulation
Fan Testing Automation
Other systems have been developed to support and verify
the simulation results as well as automate fan testing. They are:
Testing Chamber Data Acquisition and Control System
The DAQ and Control System was developed by utilising
the data acquisition hardware and a graphical programming
tool to interface with the temperature and pressure
sensors as well as the control devices. It was installed
in the testing chamber to automate fan testing.
