OR-05-05-2 - External Coupling between CFD and Energy Simulation: Implementation and Validation PDF

This paper describes the implementation of external coupling between building energy simulation and CFD. Internal coupling is the “traditional” way of developing software, i.e., expanding the capabilities of existing software by adding new modules into an existing package. External coupling, on the other hand, makes use of existing packages in different domains (for example, the thermal domain for energy simulation and the flow domain for CFD) and provides a mechanism for these packages to communicate. A summary of the latest development is presented to put external coupling into the context. The implementation of external coupling is then summarized. The paper concludes with a case study to validate the performance of external coupling, and to highlight its potential.
