Summary

The simulation of a reciprocating compressor is addressed considering it as a thermal and fluid-dynamic system. This allows employing a parallel partitioned coupled approach: several components conforming the compressor-system are identified and modeled separately. By coupling these models any compressor configuration can be simulated. In this way, each compressor component can be modeled in the proper level of detail. Latest efforts in this research line have been focused on the coupling of zero and one-dimensional models and CFD&HT models. Certain parts of the compressor can be solved by CFD&HT models, while other parts can be solved by models with less computational expenses. This approach makes an efficient use of the computational resources when the research is aimed at detailed numerical results. A new model for simulation of solid components can now be coupled as well. Some illustrative numerical results are presented in order to show the advantages of this strategy in compressors simulation.
