September 30, Dear forum, I’m trying to find the acoustic field induced by a pair of co-rotating vortices. This should be a spiral pattern, like in the attachment. To test things I use Lighthill’s classical analogy.

Set-up The velocity and pressure fields are governed by the unsteady bernouilli equation. For this case an analytical expression for the flow field exists [1,2]: The flow pressure is not needed for Lighthill so I’ve omitted it here.

Within a distance of 0. This prevents the velocity from becoming very large in a core’s center the case has very steep gradients and should allow one to use a very fine grid to accurately represent the acoustic source e.

Problem I observe an odd behaviour of the acoustic source term and resulting acoustic field when I refine the mesh. Further refining to cells makes it even worse.

How can I prevent the above from happing? Or did I implement something incorrectly? For convience, I’ve uploaded my case here: C is the solver, which includes at each time step corotatingVortices.

H to generate the flow field.
