modelPressureDropPH
Calculates the pressure drop in a radiator according to manufacturer data
Extends from Modelica.Fluid.Interfaces.PartialTwoPortTransport.
Information
Overview
Model for calculating the pressure drop.
Concept
The pressure drop is calculated according to the following equation [1].
In order to determine K, manufacturer data is used and :
With the help onf the Matlab Curve Fit Toolbox a curve y = K*x^2 is fitted through several selected points.
