Periodic Reporting for period 1 - FLAMENCO (FLAgellated MicroswimmErs’ locomotioN in Confined flOws)
Période du rapport: 2016-08-01 au 2018-07-31
Our focus is on improving the mathematical and numerical modeling of locomotion at scales that range between a few to hundreds of micrometers to provide computational tools with both a descriptive and predictive power. We are in fact guided by the ambition of improving the fundamental understanding of this phenomenon and using this knowledge to inspire biomimetic robot and the design of microfluidic devices to manipulate and sort motile cells.
An improved modeling capability for the motion of microswimmers has the potential of impacting several fields: microswimmers play a crucial role for a wide range of biological, ecological, and industrial processes, e.g. the fertilization of mammalian ova, production of algal biofuels, and the degradation of particulate organic matter by bacteria. As an example, an important and largely unsolved case is biofouling where immersed surfaces become covered by microorganisms, which affect the surface performance and can even lead to its failure.
The main objectives of this project were the training of the researcher in computational modeling of micro-swimming and the development of numerical and computational models for simulating swimming at the micro-scale and study confined and collective motion.
The interdisciplinary nature of the institutions allowed the researcher to appreciate the potential of the acquired knowledge for tackling problems relevant to field as diverse as engineering, biology, reproductive medicine and medical diagnostic.
The main scientific results of this action consisted in a thorough theoretical and numerical analysis of the available mathematical models to simulate swimming at the microscale and led to identifying strengths and criticalities of the various approaches. These results have been presented at several international venues (workshops, meeting, symposia, various institutes) as posters, contributed or invited talks and are currently under review for publication in a peer reviewed journal.
The scientific outcome of this project contributed to improve, through a better comprehension of the mathematical models, our quantitative understanding of phenomena that can be described mainly qualitatively at present. The most recent developments will potentially provide the tools and body of knowledge for controlling and manipulating microswimmers near solid surfaces.
