Abstract
The thesis focuses on multi-physics simulation of a gas inflator for inflation of airbags. The need of multi physics simulations extends to many other engineering and industrial applications and has become an extensive area of research. Main focus is on the Fluid Structure Interaction (FSI) within the field of multi-physics or coupled physics simulation. The purpose is to study the flow, the membrane deformation and the interaction between these two in order to evaluate the current design and use them in future development of the complete design.
In order to set up a complete FSI analysis, several commercial and non-commercial software were evaluated within each part of the coupled FSI analysis. Aspects such as efficiency, robustness,... (More)

The purpose is to study the flow, the membrane deformation and the interaction between these two in order to evaluate the current design and use them in future development of the complete design.
In order to set up a complete FSI analysis, several commercial and non-commercial software were evaluated within each part of the coupled FSI analysis. Aspects such as efficiency, robustness, flexibility and possibility to extend the analysis to include combustion and optimization tools were all evaluated in order to find a fast, accurate and flexible simulation tool. Reliability and error estimation were also performed being one of the most important issues during all steps of a complete FSI analysis. The high pressure gas inflators are a challenging FSI problem due to highly complex fluid behavior at extremely high pressure and velocity and the complex deformation on solid side due to high stresses.
The results show that even the most challenging FSI cases can be solved with the modern CFD and FEA tools. (Less)
