co-axial double pipe heat exchanger
 

i am following a tutorial on double pipe exchanger available athttp://homepages.wmich.edu/~leehs/ME...20tutorial.pdf

i have tried lot of time but the solution doesnt converges but the tutorial says it should converge within 650 itrations.
i need help to simulate double pipe in ansys fluent
please help:confused:

Hi,

Did you follow up the same steps as per the tutorial.

Changing mesh sizes would also affect the convergence

Yes i have done the meshing as per instruction but solution not converging...recomend me some other tutorial , if you know any
