Test Case
The purpose of this test is to compare prediction of the fractional flow in a dividing tee-junction with experimental results. The fluid enters through the bottom branch and divides into the two channels whose exit planes are held at the same static pressure.

Analysis Assumptions and Modeling Notes
The flow is steady and incompressible. Pressure based solver is used. It is seen that with increasing flow rate in the main channel, less fluid escapes through the secondary (right) branch. For analysis of results, we calculate and compare the fractional flow in the upper branch.
