HYSYS cannot calculate heat loss for pipeline heat conduction
Thread Content
It’s a very simple single-pipe system; I want to calculate the pressure drop and temperature drop. All other values have been set, but HYSYS cannot determine the heat loss due to heat conduction in the pipe
The same question – I wonder if the original poster has solved it. I seek guidance from experts.
This situation usually occurs because HYSYS calculates a pressure drop that is too high based on the pipe length and diameter you enter, resulting in an outlet pressure below 0 kPa (absolute pressure); since the outlet pressure cannot be below 0 kPa, it will display that convergence has not been achieved. This has nothing to do with whether heat dissipation is taken into account or not. So, you can try increasing the pipe diameter or decreasing the pipe length, and focus on achieving convergence first... As for whether it matches the actual conditions, that’s another issue~~~
Adding the insulation thickness should do it
