Modeling Multi-Element Systems Using Bond Graphs

Keywords

Abstract

This is the last in a series of three papers. The first paper discussed the modeling of conductive as well as convective fl ows of a single homogeneous substance through a homogeneous medium. The second paper discussed the phenomenona associated with phase change, i.e., it discussed, from a bond-graphic perspective, phenomenona such as evaporation and condensation, solidification, melting, and sublimation. This third paper deals in particular with the difficult problem of modeling multi-element systems. Together they offer a general methodology for modeling thermodynamical phenomenona using true, rather than pseudo-, bond graphs. No quasi-stationary or fl ow-equilibrium assumptions were made, such that the models generated using the proposed methodology would be kept as general as possible.
