Hi all,
I try to simulate a SCO2 radial turbine,and the condition are:
1.)Inlet:1MPa(static),reference pressure:12MPa,500K(static)
2.)Outlet:0.01 kg/s (1passage [total:11])
3.)Material>reference state property>
reference temperature:500K
reference pressure:12MPa
4.)time scale:2.5e-4
5.)model size=60mm H=30mm
6.)mesh:1.2e5 nodes(quality good)

The simulate result was finish at timesteps 5000,residuals was 1e-6 and no vibration.
The boundary condition:
a.)Outlet pressure : 0.86MPa
b.)Outlet temperature : 499K
c.)max. velocity(inlet) : 40 m/s

My question is why the outlet temperature still near 500k,temperature shuld decrease.I have read the Ansys FAQ,but still not solve the question.

By the way,is the reference state property right?
