Shadowgraph analysis of non-equilibrium fluctuations for measuring transport properties in microgravity in the GRADFLEX experiment
In a fluid system driven out of equilibrium by the presence of a gradient, fluctuations become
long-ranged and their intensity diverges at large spatial scales. This divergence is prevented …
