.BuildingSystems.Fluid.Movers.BaseClasses.Euler.power

Information

This function outputs power values as well as its derivative versus volumetric flow rate in the following steps:

These steps are designed to ensure that power and efficiency computation with the Euler number is handled correctly near zero flow or zero pressure, where

flo = 0,
η = 0,
P > 0

in the equation

η = Ẇflo ⁄ P.

Interface

function power
  extends Modelica.Icons.Function;
  input BuildingSystems.Fluid.Movers.BaseClasses.Euler.peak peak "Peak operation point";
  input BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.flowParametersInternal pressure "Pressure curve with both max flow rate and max pressure";
  output BuildingSystems.Fluid.Movers.BaseClasses.Euler.powerWithDerivative power(V_flow = zeros(11), P = zeros(11), d = zeros(11)) "Power and its derivative vs. flow rate";
end power;
