Abstract

The relation between flow rate and pressure drop was investigated numerically for a flame arrester with a crimped ribbon element. Permeability and inertial/viscous resistance factor of the micro-scaled element were obtained from a laminar simulation. Then, the porous zone model was adopted to simulate the flow in a flame arrester. The simulation results of the pressure drop were in good agreement with the experimental in the low flow-rate range. The analysis process developed in this study can be extended to different configurations/shapes of flame arresters and working fluids such as hydrogen.
