Stream Connectors – An Extension of Modelica for Device-Oriented Modeling of Convective Transport Phenomena

Abstract

Modelica 3.0 as well as other physical modeling languages have two basic variable types to describe the interaction of physical components: "Potential" (or across) variable and "flow" (or through) variable. It is shown that with these variable types it is not possible to describe in a numerically sound way bidirectional flow of matter. Other alternatives based on signal flow oriented modeling have severe restrictions how components can be connected together.
