Hi everyone.

I try to simulate MED-TVC. After made the program by Matlab, the distillate and the brine do not satisfy the actual result. I think the problem in heat transfer equation especially in Overall heat transfer coefficient and the areas. And because the data is not enough, I couldn't calculate the real Overall heat transfer coefficient and Instead I used the correlations.what's the right heat transfer equation and correlations.

next file contained heat transfer equation and correlations.any equation and any area is correct?
