This renowned International Symposium continues a highly successful series organised by the Bifurcations and Instabilities in Fluid Dynamics (BIFD) Association, which is dedicated to promoting research on instabilities and bifurcations in fluid dynamics.

The 11th edition of the Bifurcation and Instability in Fluid Dynamics symposium is jointly organized by the Gran Sasso Science Institute (GSSI) and the University of L’Aquila.

Organised biennially, the International BIFD Symposia provide a unique forum for researchers engaged in theoretical, experimental, and computational studies to present and discuss a wide range of topics in the broad field of flow instabilities.

The aim of the meeting is to showcase and debate original research as well as expository and survey studies, with particular emphasis on unsolved problems, open questions, and benchmark challenges in the theoretical, computational, and experimental aspects of stability and bifurcation theory in fluid dynamics. The symposium seeks to foster the exchange of ideas and to stimulate new collaborations, while also strengthening existing international links.

BIFD also serves as an excellent platform for early-career researchers (MSC and PhD students, postdoctoral fellows, and early-career academics) to present their work, engage with peers and experts, and expand their professional network.

All flows speak the language of instabilities! Hydrodynamic stability plays a fundamental role across science and engineering, with direct impact on the design and optimisation of equipment and processes. As a result, the study of hydrodynamic instabilities has become a well-established and central field of research.

The Symposium covers the full spectrum of instability and bifurcation phenomena in fluid dynamics — from fundamental mathematical theory, experiments, and computational modelling to real-world applications. The scope includes (but is not limited to) the following topics and their intersections:

● Classical Hydrodynamic Instabilities in Shear, Rotating and Convective Flows (Taylor-Couette, Rayleigh-Bénard, Kelvin-Helmholtz, Bénard-Marangoni, Rayleigh-Taylor, Faraday, Plateau-Rayleigh, Saffman-Taylor Jets/Wakes etc)
