]Air flow through a short or a long length of corrugated pipes can cause the pipes to emit loud and clear "tonal" sounds or "whistling". Pipes with transversely corrugated walls are used in many industrial and domestic applications because they offer global flexibility combined with local rigidity. This phenomenon of sound generation by airflow through corrugated pipes is not only the working principle of a children's toy called "Hummer", "Voice of the Dragon" or "Magic Whistle", but it can also be a severe problem in certain domestic appliances involving corrugated tubes (ex: vacuum cleaners), and in other fields of engineering such as "singing risers" in oil and gas industries, chemical industries HVAC, aircrafts and automobiles. This study deals with modeling and prediction of resonant frequencies of corrugated pipes with airflow using Computational Fluid Dynamics-Large Eddy Simulation (CFD-LES) using FLUENT software. The pressure contours for a laminar flow case using LES simulation compares well with CFD-Direct Numerical Simulation (DNS). The study also deals with pressure drag comparisons of turbulent flow case for various geometries of corrugated tubes. Copyright
