The design of silent wind turbine blades and low-noise aircraft components is impeded by the lack of suitable facilities for testing at realistic dimensions. This project revolutionizes the concept of noise measurements in wind tunnels by proposing a new microphone array, abating both the turbulent boundary layer noise and the noise radiated from the walls. Combined with modern microphone array technology this project will allow for the first time an effective measurement of wind turbine blades that are designed for minimal noise radiation.
The project consists of two sub-projects. The current subproject aims at optimizing the wind tunnel. The researcher will focus on understanding and predicting Turbulent Boundary Layer (TBL) noise radiation from the wind tunnel walls. Empirical models for TBL characteristics together with TBL measurements will be used to guide a more detailed numerical study. This latter will then be used to predict the acoustic effects of surface modifications. The researcher will propose optimum wall modifications that will be tested experimentally. Within the project close collaboration with several wind energy companies as final users of the technology is an important aspect.
The candidate should have an MSc degree in an area relevant to the subject, e.g. aerospace engineering, (applied) physics, applied mathematics, electrical engineering, materials or mechanical engineering. A combination of good mathematical/analytical and strong interest in numerical design is essential. Interest in performing experiments is also of high importance. A solid knowledge of signal processing and advanced programming skills are advantageous for this position.
