To simulate evaporation through porous media with the evaporation-condensation method in Ansys Fluent, follow these steps:

Set up your porous media: Define the porous zone in your domain where you want to simulate evaporation. Assign the appropriate porous media properties, such as permeability and porosity.

Enable the evaporation-condensation model: In Fluent, go to the "Models" panel and enable the "evaporation-condensation" model.

Define phase change settings: Set the appropriate parameters for the evaporation-condensation model, such as the evaporation rate, condensation rate, and heat transfer coefficients.

Specify the initial conditions: Define the initial temperature, pressure, and other relevant properties for the domain and porous media.

Set boundary conditions: Apply appropriate boundary conditions, such as inlet and outlet conditions for the fluid flow and evaporation.

Initialize and solve: Initialize the simulation and run it to solve the fluid flow, heat transfer, and evaporation-condensation phenomena.

Post-process results: Analyze and interpret the simulation results to understand the evaporation behavior within the porous media.

Remember to consult Ansys Fluent documentation or tutorials for more detailed information on specific settings and inputs relevant to your simulation
