| dc.description.abstract | The abitity to predict the behavior of a turbine engine and optimize its performance
is important in economic, thermal and condition obseruation studies. Fouling is one of the maior
sources oJ compressor deterioration. So, the paper presents an analysis of the ffictiveness of
online and olfline compressor washing using numerous puriQ grade waters and industrial
washing detergents. Fri* go, turbine ixial compressor blades fouling dirt of blade.surface **as
obtctined at numerous fielisites. To see the composition and consistency of typical blade surlace
fouling materials the dirt was analyzed. An exemplaty dirt formulq and blade coating procedtrre
"was
finnttlated so comparative tests can be performed using numerous cleanup fluids' To see the

btade test section was used for
ctlaning btades withfive totaily dffirent cleaning liquids. In dffirent residue experiments
the imp"act of high-purity water yersus regular water on fouling dirt was coniointly studied'
Results showed that an important means oJ-cleaning compressor blade is spraying cleaning.fluid
into a Jlowing oir stream. Every of the Jlitds w,ere ready to clean the test blade at each lov' and
high iir velocities and at toialiy different blecle incident angles. The Results shou'ed that

pr"rro, blade washing is primariiy a mechanical work and does not rely on the kind of .fluid
