Artifical Boundary Conditions for rising gas bubbles

Boundary conditions plays an important role in CFD. Disturbances from boundary conditions can have an huge impact on the quality of the computational results. However in most cases no-slip or slip boundary conditions are used as they are easy to implement and simple to use. Therefore large computational domains are needed to reduce the influence of the boundary conditions.

In this project new boundary conditions are implemented, which reduce disturbances from the boundary. This reduces the negative impact on the solution and therefore improves the results of the simulation. On the other side, the size of the computational domain can be reduced. This results in reduced need for computational resources and computational time. Thus we are able to simulate some problems which are to expensive in computational time and resources to calculate with classical boundary conditions
