I'm currently working on my Bachelor's thesis about the numerical simulation of a turbulent air flow through a rectangular channel. As part of that I'd like to compare my results to empirical correlations for the boundary layer thickness as a function of distance from the inlet for such a flow. However, I can only find correlations for a flat plate (Schlichting, White, Anderson). Does somebody know such correlations? Thanks! This is the essential part of the geometry:

I study the development of the boundary layer from the tip of the plate downstream.

There is a validation case for turbulent flow in a two-dimensional channel at NASA's Langley Research Center Turbulence Modeling Resource website. You will also find results for many turbulence models used to simulate the case such as Wilcox's standard 2006 $k-\omega$ model and Spalart-Allmaras one-equation model.

What you are looking for is a Reynolds number, there is a source that can help you. This is an extremely broad topic so it would help if you specified.
