The design of modular dynamical fluid simulation systems
2005 (English)Conference paper (Refereed)
The objective of this paper is to give an overview of methods for simulation of dynamical fluid systems. Typical applications for such simulations are the design of pneumatic and hydraulic systems, internal combustion engines, cooling systems, and air management systems for fuel cells. The governing Navier-Stokes equations are presented and from them the one-dimensional lumped governing equations are derived. Different methods for solving systems of interconnected components are presented: the state-space/bond-graph method, transmission line modelling, and CFD (Computational Fluid Dynamics) methods. Finally a method to solve the problems using the fully dynamical equations is presented. The method is to use the bond-graph method to systemise the system, and then add virtual mass to the dynamical equation in order to make the simulation system faster to solve. Results from the verification of this are presented in the results section of this paper.
