This work investigates the impact of wall corrugation on fully developed turbulent pipe flow using Large Eddy Simulation (LES), addressing a significant gap in existing research. Simulations of both smooth and corrugated pipe flows were conducted using the high-order spectral element method (SEM) within the open-source Nek5000 solver.

Key findings include the deviation of the mean velocity profile from the law of the wall, enhanced turbulence production at corrugation peaks and suppressed eddy activity in the valleys.

These findings provide both computational and physical insights into rough-wall turbulence, establishing a benchmark for future high-fidelity simulations involving complex boundary geometries.
