Abstract

Trailing edge noise is a significant contributor to the noise emissions of wind turbine blades. Thus, in this project we aim to study and understand this flow-induced noise emission with a detailed analysis of this sound source and possible mitigation strategies by employing the Lattice-Boltzmann method for a highly resolved simulation of the fluid flow and the resulting noise. We present the current status of the project - including a preliminary study consisting of wind tunnel experiments and very large eddy simulations. Based on this, the objectives for the new study are defined. A new feature that shifts the communication of the global reductions in health checks into the background, was implemented recently and it's impact is investigated in this report. We determine the setup as well as the operational parameters for production runs on Hawk to make best use of the machine.
