Hello,

I am a BE Mechanical Engineering student working on my final year (DE) project.

My project topic is “Manufacturing of an Automobile Air Filter using 3D Printing Technology.”

I want to perform CFD simulation in ANSYS Fluent to analyze:

Airflow through the air filter

Pressure drop across the filter

I have modeled the filter region as a porous medium to simplify the internal geometry.

My current setup:

Solver: Pressure-based, steady-state

Fluid: Air

Inlet: Velocity inlet (10 m/s)

Outlet: Pressure outlet (0 Pa)

Turbulence model: k-ε

Porous zone applied to filter region

I would like guidance on:

Correct porous media parameters (porosity, viscous resistance)

Whether my boundary conditions are suitable for an automotive air filter

Best practices for mesh and result validation

Any suggestions or reference examples would be very helpful Thank you.

You started a new post in the General Mechanical channel, but your interest is in building a CFD simulation so you would be better off posting in the Fluids channel.
