Modeling Membrane Separation in Water Treatment with Ansys Fluent
You can potentially model the membrane in your water treatment scheme using the porous media option available in Ansys Fluent, but with some limitations. Here's a breakdown:
Porous Media Approach:
- This approach treats the membrane as a resistance to flow based on its physical properties like porosity and permeability.
- You can define the membrane properties in the "Material" section of Fluent and assign them to a cell zone representing the membrane.
- Fluent will then calculate the flow of water through the membrane based on pressure and temperature differences across it.
