Hello,

I am simulating 3D steam turbine stator in cfx using multiphase-droplet condensation model. I have a problem regarding to temperature field. In simulation, the flow temperature on the blade wall increases (reached to 1600 K).
I have chosen no slip adiabatic BC for walls. I included viscous work term in heat transfer model option.

Can anyone suggest what is the reason of temperature increment at walls ?

Thank you in advance.

BR,
Yogini

A vague question, so I refer you to the FAQ on accuracy: http://www.cfd-online.com/Wiki/Ansys..._inaccurate.3F
