Hello all,
I am trying to create a simple 2D case of an external (atmospheric flow) - the mesh is a "square". To this domain, I would like to add a mean flow direction, as well as noise. So, this is how I thought I could approach it: Outfit three of the sides of the domain with the turbulentInlet BC and the fourth side with an inletoutlet type condition. First of all, I am not really sure if this is a good way to go about it, maybe someone has a better suggestion. Second, I would like to understand a bit better those two boundary conditions: For turbulentInlet: I know that a reference value and a fluctuating scale value have to be given. But, are the fluctuations random? (e.g. white noise) or something else? For the inletOutlet: I am not actually sure how this works or if it's the right boundary to use but essentially I need a boundary through which the flow will leave. (satisfy continuity). Thank you very much for any help you can give me! |
