Dear all,
I want to calculate the bulk temperature of convective heat transfer in pipe by Using Ansys FLUENT 17.2. I plot the value of this temperature by using massFlowAve which is available at CFD-Post. Some papers use Mass Weighted Average to calculate bulk temperature. I am trying to find CFD-Post Manual but I don't find the equation of massFlowAve. Is it Ok If I assume that massFlowAve is the same as Mass Weighted Average to calculate bulk temperature? Thank you for your help Teguh

For fluent files (cell based solver) I expect them to be the same. As long as you have outflow everywhere. When you have recirculation things become trickier.

Dear Gert-Jan
Thank you for your reply. My case is open circuit. There is one inlet and one outlet. Entrance and exit length is 15 cm. So far, there is no backflow. It seems that the massFlowAve can be applied. Thank you for your help Best regards Teguh
