The first winner is the project "Boundary layer turbulent transition in unsteady flow with application to rowing" led by Prof. C. Clanet from the LPENS/LadHyX, Ecole Normale Supérieure/Ecole polytechnique, France. The goal of the project is to establish a connexion between the acceleration of a flow along a slender solid surface, and the development of the viscous boundary layer on that surface. The onset of laminar-turbulent transition, flow unsteadiness and unsteady wave drag are some of the key physical features affecting the hydrodynamic drag of a rowing boat.

The second winner is the project "Ultrasonic monitoring of material characteristics under transient chemical/biochemical reactions" led by Dr. Y. Tasaka from the Laboratory for Flow Control, Faculty of Enigineering, Hokkaido University, Japan. This innovative project aims to monitor rheological properties, such as viscosity and viscoelasticity during manufacturing processes, by UVP-based rheometer using the ultrasonic spinning rheometry method.

And our "coup de coeur" winner for its ecological aim is entitled "Preliminary laboratory studies on microplastics’ mobilisation in open-channel flows" and led by A. Varrani from the Department/Laboratory: dept. Hydrology and Hydrodynamics, Institute of Geophysics, Polish Academy of Sciences, Poland. The proposed project deals with the transport of small plastic fragments in streams and rivers, specifically the study of the conditions initiating microplastics’ transport at the stream bed and their deposition, which is essential for modelling and forecasting of fragments’ fate into fluvial systems.
