Laboratory for Flow Instabilities and Dynamics

Thomas Kaiser

After his master's degree in aerospace engineering, Thomas worked on thermoacoustics and hydrodynamic stability analysis during his PhD thesis in Toulouse. Currently, as a post-doctoral researcher, he is dedicated to developing methods based on the linearized fundamental equations to better understand fluid dynamics, especially flame dynamics. Similar methods have been used in science for over a century to study numerous instability mechanisms and fluid dynamics. In recent years, advances in computer technology have significantly increased the computational capabilities for numerical applications, bringing their use in industry within reach. It is Thomas' overall goal to make them usable for industrial applications. This is because linearized methods hold particular promise for advancing future technologies, such as green hydrogen combustion and flow control in wind and water turbines.
