How to get average liquid temperature in annular region along flow direction?

  Hello,
  Fluid flows over a cylindrical rod and the flow channel is annular. Then how can I calculate the average liquid temperature in the flow (axial) direction?
  I am planning to simulate this considering a 2D axisymmetric problem. Moreover, is there any problem to use volumetric heat generation (W/m3) in 2D?
  Regards,

  No problems running 2d-axi, just read the documentation to understand the requirements and equivalent sector.
  Average temperature along the axis is a little more complex as you'll need to find the mean at a series of positions. Have a look at surface reports.

  Hello Rod,
  I can get the average liquid temperature at the inlet and outlet using the surface reports. But, I am planning to get average temperatures in several locations along the flow direction. Can you give me any idea to get the average temperature?

  You'll need to use surface monitors, do a few tutorials as they'll be covered in those.
