Flow Field Simulation and Experimental Evaluation of Carbon Canister Based on FLUENT

The computational domain model of a certain carbon canister was established, the internal structure of carbon was simulated by porous medium and the internal flow fields of the carbon canister's adsorption and desorption processes under two different operating conditions were numerically simulated by FLUENT. The results show that, the PSID between adsorption orifice and atmospheric orifice of the two absorption processes were 3.15 mbar and 8.16 mbar; the PSID between desorption orifice and atmospheric orifice of the two Desorption conditions were 10.9 mbar and 23 mbar, and the pressure drop of adsorption orifice were 3 mbar and 6 mbar.The numerical simulation results of the four processes are accordant with the experimental data, and the results meet the demand of the pressure drop.
