Role of interfacial stabilization in the Rayleigh-Bénard convection of liquid-liquid dispersions
Understanding how emulsions transport heat under buoyancy forcing is essential in many natural and industrial flows, yet the role of interfacial physics remains poorly explored. Using mesoscale lattice Boltzmann simulations, we compare stabilized and non-stabilized liquid--liquid dispersions in Rayleigh--B\'enard convection. While their global heat transfer is similar, stabilized emulsions sustain stronger small-scale heat-flux fluctuations, revealing how interfacial stabilization reshapes convective dynamics at the droplet scale.
