講演タイトル | "On The Boundary Between Theory and Experiments: From chemically-driven viscous fingering to reaction fronts in microgravity" <要旨> Science is always challenging, particularly when one must choose between following a purely theoretical or experimental path. But sometimes, being right in between can help us find better solutions to scientific problems. This presentation unfolds in two parts, each showcasing a unique problem at the interface of theory and experimentation. In the first part, we will examine a system where pattern formation is induced by complex chemical reactions [1, 2]. Here, we will study its behavior experimentally and use numerical simulations to understand the mechanism behind its dynamics. In the second part, we highlight the importance of prior experimental experience in shaping realistic mathematical models. Specifically, we investigate how the premixing of the chemical species influences the behavior of A + B → C reaction-diffusion-advection fronts under microgravity conditions. We illuminate how this experimental artifact impacts the characteristic properties of these fronts [3]. This talk extends beyond physical-chemical phenomena; it serves as guidance for those navigating their scientific paths, illustrating the richness of exploration at the confluence of theory and experimentation.
