The obvious conclusion is your convective BC is wrong. I suspect it results in almost no heat transfer and therefore no heat wake. Check you HTC and temperatures.

CHT should work fine into the fluid, so a heat wake should form if the conditions are correct.

:) I don't know what you are trying to learn from this simulation, so cannot answer that.



OK, so that shows that the heat is being convected away in a fluid domain, but what about in a solid...

They might have introduced this in V13. It is simple to check, just put a hot spot in a solid body and move it and see what happens. Do you see a hot wake behidn the tool?

I understand now. In fact I was part of a team which looked at friction welding of steering racks (for automotive stuff) years ago so I know a little about this process.

What version of CFX are...

Unless you give us some idea of what you are modelling I cannot help you. That is why I did not bother replying. I am not an expert at friction stir welding and I have no idea of how you propose to...

If the interface has no gaps then you do not need to set any boundary condition. Have a look at the tutorials for how to set up rotating machinery simulations.

No. You model the solid domain ONLY if you require the temperature distribution in the solid. If you are modelling temperature in the fluid but know the condition of the solid then you do not need to...

Hi,

This simulation is a basic application of rotating frames of reference and really is not that hard when you understand the basics. However, explaining what to do on a forum is difficult. Have...

Hi,

You don't need to model the solid region (which I assume is the ellipse) if you are not modelling heat transfer. If this is the case then you will have two fluid regions, one stationary and...

Hi,

I cannot picture what you are describing. Can you draw a diagram?
