Analysis of the heat transfer fluctuations in the Rayleigh–Bénard convection of concentrated emulsions with finite-size droplets

Abstract

We numerically study the heat transfer fluctuations in emulsions with finite-size droplets under Rayleigh–Bénard convection. As droplet concentration increases, we observe extreme heat flux fluctuations arising from collective droplet motion. We analyze their localisation, extension and duration.
