Hi Guys,

I am asking for advise related to domain dimensions. I want to conduct simulations on aircraft wake turbulence. I want to model a block-shaped domain, that contains a model of a wing (a have attached a basic idea). The boundaries will be an inlet, symmetry on the side that the wing is attached to, and the rest will be openings.

I am asking for advise concerning the size of the block shaped domain in relation of the wing-geometry.

for example:

The domain should have a length of 5 times the wings chord before the wing and 50 times the wings chord behind the wing. The height of the domain should be 2 times the span of the wing und the width should be 3 times the span.

Does anyone have suggestions or experience how big the domain should be to be able to depict the wingtip-vortecies while being as small as possible to not waste computational power.

Your advise would be greatly appreciated! :-)

I have looked into the literature but have not found something useful yet...
