Hi,
I'm trying to design a stirred reactor using ANSYS/Fluent, but I'm coming across a problem that I just can't find a solution.
Our reactor is being modelled as 2 zones: zone 1 is the outer cylinder (the reactor) and zone 2 is the shaft+blades removed from an inner cylinder. The problem is: in the contact zone between both zones, Fluent seems to be inconsistent. As you can see in the pictures below, the edges of the inner cylinder (the part that rotates) are pretty much detectable, as if it were a wall or a complete different body from the reactor. It is also possible to notice the velocity in the edges of the inner cylinder: it is faster "inside" the cylinder and "outside" it drops to almost 0 instantly.
Can anyone give me some advice? Any help will be very muchly appreciated
