Hello ,
Very interesting thank you.
Convective heat flux cannot work though as it is not rotating.
Another simulation now running stuck a 5min for only 120 seconds with 5 seconds interval.
Shorter time doesnt work also.
I think some basics are missing.
Is there a way to easily pick a temperature or the average temperature a un certain point in time of the pipe? for example 5 minutes ? A tutorial for that ? It is all about the speed of the spinning pipe to cool down to ambient temperature with or without the fan.
Only this would be good enough to compare and start real design with the software.
Thank you again, your help is really appreciated.
