Towards coupling computational fluid dynamics with system dynamic simulation softwares

Following the increasing performances of the computer technology, Computational Fluid Dynamics (CFD) enables nowadays the accuracy/computing time ratio to be acceptable. Whereas stationary approaches using CFD have been applied successfully in order to determine some parameters of required by macroscopic models, only a few approaches have proposed to link local CFD simulation with macroscopic system simulation. Pneumatic system modelling can become very complex, requiring an extensive experimental approach when some phenomenon has to be accurately studied. The purpose of this work is to show the interest of coupling both CFD and system simulation approaches in order to improve the knowledge on the system.
