interTwoPhaseCentralFoam - yet another compressible two-phase solver
 

Dear colleagues,


after some efforts our team has issued first version of solver for simulation of compressible two phase flow with gravity & viscosity. The solver differs from standard OpenFOAM programs (compressibleInterFoam) by employment of central Kurganov-Noelle-Petrova schemes for convective fluxes, ACID (acoustically conservative interface discretization, https://doi.org/10.1016/j.jcp.2018.04.028) and by usage of mass-flux based pressure equation.


interTwoPhaseCentralFoam was tested for several Riemann problem, dam break problem and interaction of water cylinder with gas shock wave.


First version is located in the branch "exper/2phase" of repository https://github.com/unicfdlab/hybridCentralSolvers which is compatible with OpenFOAM+ 2012. Version for OpenFOAM 2112 is on road.
