[QBA]

Hello,


I'm doing FSI simulation using Abaqus CFD and Abaqus Standard modules.



Boundary condition:
fluid inlet velocity = 6 m/s
fluid inlet temp = 293K
outlet pressure = 3bar
solid and fluid initial temperature = 1100K

No slip on solid part in CFD module.



After 60 seconds of simulation temperature dropped by only 20K. I know from data, that temperature should be lower by 70K.



I already checked material properties few times.

I have no idea what I do not include in the simulation



Thanks in advance
