Temperature and heat flux wall boundary condition

L. Hamid · February 1, 2014, 05:51

Dear All,

In my model, I have a coil which transfers the heat flux 5000 w/m2 to gasoline. I set the wall of coil boundary condition by this heat flux. After convergence the model, I checked the surface temperature of the coil. It was 1000 K. But In real, the surface temperature of the coils shouldn't exceed 400 K. How can I control the temperature and heat flux of the coil?

Any help would be appreciated

I think you are asking the wrong question.

The real question is why your simulation gives different results than the "real" world. Check your material coefficients, for example.

If your simulation does not give the result that you expect, you should not just change settings until you get wat you expected... You should check if your expectations were right, and find out what is the reason that it is different!

Tank you for your reply. I'll check.
