IMAC XLIII Conference in Orlando, Florida, USA: Modal analysis in fluid mechanics

Leave a Comment / Conferences, Fluid mechanics /

Modal analysis is typically associated with structural mechanics, where dynamic systems oscillate in various modes, each characterised by a specific frequency. These modes represent the way the structure oscillates. But why did I travel all the way to Orlando, Florida, for this conference? As a fluid mechanicist, this may seem an unusual choice. However, the […]

Shockwaves in cloud cavitation from high-speed imaging

Leave a Comment / Fluid mechanics /

Shockwaves in cloud cavitation can be visualised using high-speed imaging from both top and side view. While this technique does not yield direct quantitative data, it captures pixel intensity variations that correlate with local void or air–liquid fractions—offering valuable insight into flow dynamics. Data such as characteristic lengths, times or velocities can be extracted from

SPyOD package: a python implementation of the SPOD technique

Leave a Comment / Coding, Fluid mechanics /

In a collaboration between the Technische Universität Darmstadt and Technische Universität Berlin the SPyOD package is implemented in python and is freely usable for everyone via git. You can explore the code, contribute, or use it in your own projects via the following link: https://github.com/grigorishat/SPyOD. This technique was introduced by M. Sieber, C. O. Paschereit
