I would like to see the heat transfer between the pipe-fins-solar salt produced by the inner wall(of the pipe) at 300 ºC in this model!!

Why i dont get any result???I think the result should be different.

Please,i would be grateful of any suggestion!!

Hi,
The diameter of your tank is about 520 meters and diameter of the tube is about 80 meters. Are those real sizes?

Hi!!Thanks for your reply!!!

No,it shouldnt be like that.I made the design in Inventor and imported it into comsol.But when i did the design,the measures where 500 mm and 50 mm or something like that,but not so high(meters).

Do you think is there anything wrong with the sizes??I will check it!!!

Hi,
Click on the Geometry node (in your mph file). Note Lenght unit: m (you can change it) and the scale on axes in the Graphics window!
