'Catalytic Converter Exhaust-Porous Media' simulation project by Ali_Arafat


I created a new simulation project called 'Catalytic Converter Exhaust-Porous Media':

Automotive Catalytic Converter exhaust flow analysis using Porous Media.

More of my public projects can be found here.


Catalytic Converter exhaust flow analysis using Porous Media

The analysis compares the flow through an exhaust pipe with and without a catalytic converter.

The catalytic converter is modeled using Porous Media model 'Darcy-Forchheimer' with the following properties:

Porosity: 0.5

mean Diameter: 2e-3 m

Permeability: Isotropic

The local direction (e1) of the Porous Zone is aligned at an angle of 30 degrees CW to the Y-axis as shown in the figure above.

The coefficients ‘d’ and ’ f ’ are calculated from the formulations:

where ‘phi’ is Porosity and ‘D’ is mean diameter.
