Multiple-field systems dynamic modeling, part III: Fluid field physical decomposition

In this study, a new fundamental modeling framework for compressible fluid field is proposed by means of which a two-way dynamic coupling between the solid and fluid fields can be attainable for identically-modeled solid field. To this aim, using the physical decomposition framework proposed in [1], the general dynamics of the fluid field are extracted from the conserved reversible and irreversible interactions of the energetic components of the involved physical domains. The physically-decomposed power network of the fluid field makes it possible to control and manage the data transactions of each physical domain of the field individually. The added capabilities of the proposed physical modeling approach provide a novel feature that can be used for multiple-field system dynamic studies by providing the possibility of continuous data transactions between coupled fields.
