Abstract:
The highly dynamic process in a pyrotechnic inflator and in a canister-airbag system was simulated by using two compressible gas thermal energy numerical models. First a 20D model was used to simulate flow through the inflator porous media; then results from the first model were used as input to a second 2-D model to computer pressure, temperature and flow patterns in the airbag. Results show a complete picture of the dynamics of the airbag inflator-canister system during deployment.
