negative pressure in mixing tank
1 Attachment(s)
hi i am simulating single phase flow in a stirred tank. i am getting negative values for pressure in the tank domain. why does it happen?
does that indicate that the flow is taking a turn in the opposite direction? if its so then near the walls also i should have negative pressure as the fluid flow diverges at the vicinity of baffles...
i am more confused with it...:confused:
