Description

Small-scale fluid mechanics play an important role in virtually all living systems. Biological processes taking place at very low Reynolds numbers pertain to individual cells (swimming of bacteria or sperm cells) as well as to cell collectives and even groups of larger, multicellular organisms. Classical theoretical explorations and efforts to model fluid flow at low Reynolds number have long been limited to single cells swimming through a Newtonian fluid. Biological problems, however, often involve complex environments and/or systems containing more than one cell or organism, and traditional models have yielded only approximate answers to these problems. Recently, the development of computational tools has spurred advancement in the study of low Reynolds number fluid mechanics in biological systems.
In this minisymposium, we focus on both locomotion in complex materials (such as soil or viscoelastic fluids) and the emergent collective dynamics observed in organisms at different scales by expanding on existing fluid models, developing better-performing algorithms, and integrating behavioural and fluid mechanical models.
