Strong interest in the motion of active swimmers in turbulent flows is triggered by problems such as sea search and rescue algorithms or diffusion of microorganisms in aquatic environments. For example, the patchiness in the distribution of phytoplankton can be related to the exposure of the microorganisms to turbulent flows. Recent progress in laboratory modelling of turbulence and the fabrication of artificial swimmers using Janus particles makes it possible to study these processes in the laboratory. This project is intended to undertake the first such study. The project is expected to help understand the impact of particle motility on turbulent dispersion.

人们对主动游泳者在湍流中的运动产生了浓厚的兴趣，这些兴趣是由诸如海上搜索和救援算法或水生环境中微生物的扩散等问题引发的。例如，浮游植物分布的斑块可能与微生物暴露于湍流有关。最近的进展，在实验室模拟的湍流和制造的人工游泳者使用Janus粒子，使人们有可能在实验室中研究这些过程。本项目旨在进行第一次此类研究。该项目预计将有助于了解颗粒运动对湍流分散的影响。
