Abstract
Alfdex is the market leader for high efficient solutions for removing particles from
crankcase gases in diesel engines. Alfdex aims to expand to new markets by
exploring the possibility to adapt their technology to clean the intake air of diesel
engines. When designing and developing air cleaning systems, the two most critical
parameters are the pressure drop and the cleaning efficiency. A Computational Fluid
Dynamics (CFD) model of the current disc stack centrifuge was developed.
However, the CFD model was not validated by experimental data. Thus, the
pressure investigation was inconclusive. A prototype featuring a rotating wall was
tested under different conditions to examine if the cleaning efficiency fulfil the
market... (More)

However, the CFD model was not validated by experimental data. Thus, the
pressure investigation was inconclusive. A prototype featuring a rotating wall was
tested under different conditions to examine if the cleaning efficiency fulfil the
market requirements for air filters. The testing condition of the prototype followed
the guidelines of the ISO 5011 excepting for the choice of the contaminant that was
not Arizona dust as specified in the standard. A maximal cleaning efficiency of
96,7% was obtained at 8000 revolutions per minute (rpm) and when injecting oil in
the inlet of the centrifuge. Further design changes should be undertaken in order to
increase the cleaning efficiency to meet the market requirements. Lastly, the
economic implications of changing to a maintenance free product were discussed. (Less)
