corona discharge plasma simulation to model EHD/EAD propulsion
I am developing a custom OpenFOAM-13 application to simulate electrohydrodynamic (EHD / EAD) propulsion, coupling electrostatic body forces with the Navier - Stokes transport. My simulation uses electrostatic body forces coupled with Navier - Stokes equations and transport equations for multiple charge species.
One numerical challenge that I have partly solved is the appearance of un-physical negative charge densities. I extended the Courant number provided by OpenFOAM to suppress these and have successfully controlled negative densities https://paracpg.gitlab.io/wikis/cfdpages.html#controlling%20negative%20densities:%5B%5Bcontrolling%20negative%20densities%5D%5D (see the video here https://paracpg.gitlab.io/wikis/cfdpages.html#controlling%20negative%20densities:%5B%5Bcontrolling%20negative%20densities%5D%5D ).
As you can see from the video this approach works quite well, however I would prefer to eliminate the underlying numerical issue.
I am looking for collaborators with experience in areas such as:
* OpenFOAM solver development
* Finite-volume discretisation and numerical stability
* Drift-diffusion or plasma transport models
* Electrohydrodynamics or electroaerodynamics
* CFD algorithms for strongly coupled multiphysics problems
If you have worked on similar problems - or are interested in exploring them together - I would be very interested in hearing from you. I am happy to share details of the implementation, discuss ideas, and collaborate on improving the numerical formulation.
