Researchers of the Project M.Sc. However, the details of this mechanism are not quite understood yet, and their experimental analysis is rather difficult. The aim is to analyze the effects of turbulence structure at nozzle exit on the primary break-up process within the jet. It is also intended to manipulate the turbulence of the nozzle flow by trip-devices, both within boundary layer and in the center. The numerical method used for the simulation is of finite-volume type and uses unstructured grids with arbitrary polyhedral control volumes.
Surface tension is implemented as a body force which acts in partially-filled cells.
The preliminary results obtained in various laminar jet break-up simulations have shown that the method is suitable for the above task, provided that the grid in the interface region is sufficiently fine.
