This paper studies sound waves generated in corrugated pipes by using computational fluid dynam- ics. The author did not have any prior experience in computational fluid dynamics and therefore a substantial part was dedicated to theory in computational fluid dynamics. On this background, this paper aimed to develop the necessary boundary conditions and solver settings in order to simulate the problem using OpenFOAM. The main result consists of two cases, where the first case studied the flow over a single corrugation and the second case a study of the flow through a corrugated pipe. It was found that the first case was able to predict frequencies matching previous work. The second case was not able to produce the features connected to singing in corrugated pipes. This is largely attributed to how the inlet boundary condition was set.
