Temperature Miscount

Mullop · February 21, 2014, 07:20

hello!!
i am working a simulation on radial gas turbine. i am using energy and k-epsilon model. setting boundary on inlet as mass-inlet and outlet as press-outlet.
after running the simulation, i find that the temperature outlet is just the same with inlet.
is there any suggestion?

Suggestion 1: your simulation correctly described what is happening, and the temperature at the outlet really is the same as in the inlet.

Suggestion 2: you did not calculate the energy equation. Check at 'Models' if the energy equation is really on, and check at 'Solution controls'->'equations' if it is also calculated.

Is the temperature everywhere in the domain the same, or only at inlet and outlet?
