Dear all,
The following model may prove useful to somebody (other than myself) who wishes to calculate the average of some scalar value as a function of axial distance. In this case it's the bulk fluid temperature.
The model was made on COMSOL 4.2.0.228 with basic 'classkit' licence.
It does this:
- Calculates the surface integral of temperature in the xy plane.
- Displays a line graph of the average xy temperature variations in the axial z direction using a general projection.
Also, it has fully developed inlet flow specified with boundary PDE solution.
The general projection method used relies on the symmetry of the geometry, it takes a slice right down the middle of the pipe to calculate the average temperature at different axial positions.
THE PROBLEM:
If I cut the pipe in half the technique used to calculate the bulk average temperature would no longer be valid.
Does anyone have any advice for how average bulk temperature could be calculated for a semi-circular geometry?
Thanks,
Adam Parrott
