modelFlowCoefficientCorrection

Flow coefficient correction factor due to the contaminant accumulation

Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).

Information

This model calculates the flow coefficient of the filter by

dpCor = brat,

where b is the flow resistance coefficient, which must be greater than 1, rat is the relative mass of the contaminant that is captured by the filter as described in Buildings.Fluid.AirFilters.BaseClasses.FiltrationEfficiency.
