.IBPSA.Fluid.Actuators.Valves.TwoWayQuickOpening

Information

Two way valve with a power function for the valve opening characteristic. Valves that need to open quickly typically have such a valve characteristics.

This model is based on the partial valve model IBPSA.Fluid.Actuators.BaseClasses.PartialTwoWayValve. Check this model for more information, such as the regularization near the origin.

Revisions

• April 4, 2014, by Michael Wetter:
  Moved the assignment of the flow function phi to the model instantiation because in its base class, the keyword input has been added to the variable phi.
• March 27, 2014 by Michael Wetter:
  Revised model for implementation of new valve model that computes the flow function based on a table.
• February 20, 2012 by Michael Wetter:
  Renamed parameter dp_nominal to dpValve_nominal, and added new parameter dpFixed_nominal=0. See IBPSA.Fluid.Actuators.UsersGuide.
• March 25, 2011, by Michael Wetter:
  Added homotopy method.
• June 3, 2008 by Michael Wetter:
  First implementation.
