Hello everyone,
I am trying to simulating heat transfer in counter flow heat exchanger (single phase, no solid domain) by considering water as working fluid. In my simulation residuals of all the equations are converged bellow 10e-4 except energy equation (please see the attached figure), When i checked domain imbalance H-Energy imbalance is around 9%. My question is 1.what is the cause because of which energy term is not converging even after 3000 iteration. 2. Can i consider this solution as converged (even though domain imbalance of energy equation is around 9%) http://s27.postimg.org/5o8lm6bfn/final.png |
