Intake Manifold Convergence Problems
I am designing an Intake manifold for my university's Formula Student Team and have encountered a problem with mass flow convergence at the end of the runners. The image below shows my issue, the solver seems to give a realistic result (the mass flow rates should be near equal) after the first 50 or so iterations but then it fluctuates randomly and gives bizarre results.
I have an equal pressure drop between the 4 outlets and the inlet and am using a pressure based K-e turbulence model. Any help would be much appreciated. Mass Flow Convergence: http://www.cfd-online.com/Forums/mem...onvergence.jpg Geometry: http://www.cfd-online.com/Forums/mem...3-geometry.jpg |
