Polymorphic Modeling Applied to Vehicle Thermal Management 2000-01-0293

The modeling of thermal phenomena in transient state in a vehicle, typically the studies of heat exchanges in the engine or the heat exchange in the exhaust line leads to the use of nodal methods or lumped parameters in systems approach. This lumped parameters vision has led to important formalization studies these past years leading to two important concepts: the multiport concept of which bond-graphs constitute the theoretical framework, and the polymorphic modeling concept leading to the definition of a minimum of basic elements allowing to build a maximum of situations.
This article proposes to demonstrate how these concepts have been used to bring about the development of a library of basic elements. Its application is demonstrated by the modeling of the different modules composing the engine (lubrication, cooling, exhaust and metal masses).
