Impermeable Surfaces or Wake Reflection

[P-Nishanth]

Hello,
I'm working on a case involving a propeller hovering above a ground plane. I would like to simulate how the wake evolves near the ground, but currently, the particle field appears to pass through the ground plane without interaction.

Is there any way to make a surface act as impermeable or to reflect the wake, either physically or visually? I'm looking to capture realistic wake-ground interactions, particularly near-hover scenarios.

Any guidance or suggestions would be greatly appreciated!

Hello P-Nishanth,
Perhaps you could try Byuflowlab's FLOWPanel.jl?

Hey Allan,

Thanks for that, I did come across it, but I don't think I can perform unsteady simulations on FLOWPanel. I need to model a propeller spinning near the ground surface. Do you know if it is possible?

The authors developed and employed a panel method as a key part of their Actuator Surface Model (ASM) to introduce solid boundaries (e.g. duct and centre body) into FLOWUnsteady. However, this part of the code is not currently available, so it may be necessary to modify the source code to incorporate FLOWPanel.
