Hello SW FS users,

I have done a SW model and i am trying to simulate a water tank heated via a serpantine.

I made it a time dependant simulation and left it like for 1 hour physical time but i can see that there is just not heating enogh. The water in the tank should get like over 40 degreece centigrate but it goes like on the simulation like 32......

Set all materials, set heat transfer coeficient ( calculated manually) set the input / output temperatures and flows...

Can someone give me a clue what it is going wrong and not heating the water.

Another thing that is desturbing me is that sometimes the temperature at the outlet of the serpantine is not rising at all and when looking an plane pictures while calculating, i see some flow going out of the serpantine even when it is absolutely closed. What might this problem consists of ?

Thank you...

I am looking forward to reading from you...
