Hi All,

I have a steady state setup with translation. Several objects move with a conveyor belt in a moving frame of reference, through multiple chambers that are in a stationary frame. In one chamber, the air is heated.

My problem is that I have two veloctity fields: a velocity relative to stationary frame and just velocity. This is the relative velocity, relative to either stationary or moving frame.

Now I expect my temperature to mix up in the velocity in stationary frame, meaning that in the moving frame, the hot air is moving with the obtsacles. But this is not the case. It is moving in opposite direction.

So, the temperature is mixed in the wrong velocity field. Does anyone know a magic button to get realistic results? To let Fluent perform mixing in Velocity in Stationary Frame?

I know the answer is transient. But a steady state, i.e. photo, should also be possible, not? Moreover, it would be a very good method to obtain an intiial guess for a transient anaylsis. If I would take my curent end-result as initial guess for a transient anaylsis, I would be far off.

And for your information: in CFX, I notice the same problem.
And forgive me the coarse mesh etc. It is just a simple test to find the correct settings.

Regs, Gert-Jan
