CFD T section pipe flow benchmarking

This document outlines computational fluid dynamics (CFD) simulations of river channel bifurcation. It discusses grid independence studies using different mesh sizes and evaluating reattachment length. Parameter studies vary fluid (water vs hydrogen), discharge ratio, and Reynolds number. Results include velocity streamlines, skin friction plots, and vorticity profiles. The conclusion compares results to benchmark studies and analyzes how discharge ratio impacts bifurcation flow patterns at constant Reynolds number.
