SCWR heat transfer deterioration phenomenon

[Davsik]

Looking for people interested in this topic for discussions and probable scientific cooperation

 

[Astronuc]

Please describe the problem. Is one referring to deterioration of the heat transfer surfaces due to corrosion? In-core, ex-core surfaces, or both?

I believe their is a fair amount of literature with respect to waterside corrosion of metals in superheated and supercritical coal-fired systems.

 

[Davsik]

The phenomenon is interesting from the thermal hydraulic point of view not corrosion but due to buoyancy forces or acceleration. There is not that much publications in fact and even less data on experiments.

Is one referring to natural circulation conditions or forced convection?

 

[Davsik]

Forced convection is more interesting. The nature of the phenomenon sure is of top interest but as I know it's said not to be understood by now. Then the prediction and onset. Experiments and calculation methodology etc.
