FLUENT Erosion DPM (Methane with Sand) - Strange Erosion Contours
I intend to model sand laden flow in a pipe of a certain complex geometry, and have more less followed the tutorial here (www.cfluid.com/batch.download.php?aid=642) except with a different erosion correlation (Det Norske Veritas's) and with a different flow condition of methane gas instead of water. The computed velocity flow field seemed fine.
Below are the velocity contours and the erosion contours I computed, of which the erosion contours are obviously wrong (negative erosion? :confused:). However, I am unable to find the problem with my simulation and hope that someone here can enlighten me.
Many thanks in advance.
Could you please send me the tutorial I cannot access the link ?
Can you show us the correlation you used and specify which parameters did you input in the wall boundary conditions for walls?Probably the problem is there (equation or units).
If I have 2 phases
-Primary Phase - water
-Secondary Phase - CaCO3
Can Accretion Model simulate the particle or granular of CaCO3 deposit to the wall which the excessive CaCO3 enough to block primary phase and cause clogging ?
You can see my attachment for explanation.
