Masterthesis opportunity in our group

The FLOW research group is investigating the dynamics of flow fluctuations near solid surfaces for their relevance to trailing-edge noise, which is the main source of noise pollution from wind turbines. In such applications, the addition of porous material to the surface is known to reduce the emitted noise, but the physical mechanism behind this noise reduction remains to be clarified.
The main approach used in our group to investigate these phenomena is based on linear stability analyses of the mean flow, which extract the dominant coherent structures in the turbulent flow and determine their role in the noise generation process. However, the presence of porous material and its influence on the coherent structures is currently missing from the linear stability tools developed in the FLOW group.
The aim of this Master’s thesis is to include the effect of porous media in the linear stability analysis of turbulent flows.
