🔬 Expanding our CFD Validation Series! 🔬 Have you ever wondered how turbulent flows behave close to the wall? Understanding these complex patterns is crucial for many engineering applications. Let us validate them! Part 5: Turbulent Channel Flow Turbulent Channel Flow is a critical benchmark for studying wall-bounded turbulence. It helps us validate and improve our models to accurately predict behavior in turbulent boundary layers, which is essential for applications in industrial processes. For detailed parameters, results, and analysis, check out the attached PDF. We look forward to hearing from you again! What benchmark cases would you like to see us validate next?

Love it 😎
This is one of the best benchmarks for near wall validation. Great job! 👏 May I ask if you also have WALE subgrid? Is it possible to compare to the same for the similar lattice size and timestep? Using FVM I experienced a considerable difference between smagorinsky and WALE for similar problem with heat flux from lower wall. WALE was working much better for the same y+. Smagorinsky filter sometimes is killing the correct vortexes.
