Acoustic streaming solver¶
acousticStreamingFoam is based on pimpleFoam,
a transient solver for incompressible, turbulent flow of Newtonian fluids. acousticStreamingFoam includes an non-linear acoustic pressure solver and
an acoustic streaming source term to pimpleFoam.
Installation¶
Pre-requisites:
A working installation of OpenFOAM 9.
In the acousticStreamingFoam/applications/solver/helmholtz/acousticStreamingFoam directory, run:
$ wmake
Running the application¶
In the case directory, run:
$ acousticStreamingFoam
Theory¶
Full details of the theory behind the solver implementation can be found in G.S.
