A number of components include Deterioration tabsheets for specification of map modifiers representing the effect of deterioration. Refer to literature for quantification of deterioration effects. A good way to analyse deterioration effects is to use steady state series calculations for parameter sweeps with varying deterioration map modifiers.
A typical turbine deterioration case can for example be represented by a 4% decrease in turbine efficiency combined with a 2% increase in massflow. A typical compressor deterioration case (fouling) can for example be represented by a 2% decrease in compressor efficiency combined with a 2% decrease in massflow.
