Biomechanics of intra-oral water flow generation in fish (IOFLOW)
This 3-year project is funded by an "Accueil de Chercheurs de Haut Niveau 2015 (ACHN 2015)" grant from the Agence National de la Recherche (ANR), and will start in the summer of 2016. The overall aim of this project is to provide a better understanding of the dynamics of intra-oral flows in fish during food capture and respiration. The IOFLOW team will quantify intra-oral flows in fishes by combining computational model simulations (CFD), biplanar X-ray videos of feeding and respiring fishes, and flow visualisation experiments.

A new article on the dynamics of suction feeding by newts was published today in the journal Scientific Reports. Using computational fluid dynamics, we tested how the annually changing shape of the mouth of newts influences suction-feeding flow patterns. The article can be viewed here.

The new computer (Dell Precision 7910; 2 x 18 processor cores, 128 GB RAM) for computational simulations (CFD, stuctural mechanics, fluid-structure interaction etc.) is now operational at the FUNEVOL laboratory. It will be running the ANSYS software for the CFD-simulations during the IOFLOW project.

A new article on suction-feeding kinematics and hydrodynamics in mudskippers was published today in Biology Open. We studied how mudskippers, who predominantly feed on land, still manage to feed underwater by generating suction. The article can be viewed here.
