Preview of Non-Reflective Boundary Condition in TwinMesh 2018

Preview on new features in TwinMesh 2018: we have implemented non-reflective boundary conditions (NRBC) in ANSYS CFX via User Fortran in a stable and robust way so that they can be used for positive displacement compressors instead of the standard openings which are reflective (RBC). While RBC lead to standing waves, especially at pressure side with mass flow strongly pulsating and even flow reversal, NRBC allow pressure fluctuations from pressure port to travel to the outlet and leave there without any artificial reflections so that mass flow is more uniform and realistic.
