About this position
PhD position at the University of Twente in the Netherlands on indirect combustion noise, with a strong focus on fluid mechanics, computational fluid dynamics (CFD), and aeroacoustics.
The project aims to improve the understanding of indirect-noise generation, especially for hydrogen-fueled systems. The research will begin with numerical analyses of a previously used experimental setup operated at DLR, using non-reacting-flow modelling to assess the validity of simulations for reacting-flow systems. The work includes comparisons of lower-fidelity compressible-flow methods such as Euler and URANS against high-fidelity LES results, followed by simulations including combustion of methane and hydrogen. The resulting datasets will support theory development and analytical/semi-analytical modelling.
Research objectives include CFD studies of vorticity inhomogeneities, comparison of Euler/URANS/LES simulations for entropy-vorticity interaction, quantification of combustion effects on noise spectra, and development of analytical models for indirect noise.
The post also mentions secondments to TU Delft in the Netherlands for about 3 months and ETH Zurich in Switzerland for about 2 months.
