enthalpy in segregated and coupled
 

Hi, I try to simulate the same case using both segregate and coupled solver.

The results deviated largely. I did notice that the enthalpy for coupled is around 300.000 J/kg, while for segregated only 2900 J/kg.

I already activated the viscous heating and other energy equation's components in segregated in order to resemble the coupled solver.

can somebody tell me what is the reason for this?

I activated the energy equation on both solver. in solve -> control -> solution for segregated solver, the energy eq showed up, but not in coupled solver.

anybody can help?

Hi!

are the reference values set correctly? are they the same for both cases??

yes, the reference values are the same except for the enthalpy. the segregated and coupled solve count enthalpy differently although i set all parameters the same. that's why i'm confused.....
