Visualizing Bubbles Within a Rayleigh Bénard Convection

The Rayleigh Bénard convection, where a fluid is heated from below and cooled from above, is an important mechanism of mass and heat transfer in nature and in numerous industrial applications. One can cite geophysics, astrophysics, meteorology, heat exchangers, multilayer walls in buildings and cooling of electronic components for example. In the present work, by considering bubbles inside the fluid flow, we aim to investigate the effects of the presence of bubbles on the heat transfer rate. In this visualization, bubbles are shown in between the shifting temperatures, rendered as a volume. Fluid simulation by Abbas Moradi Bilondi and visualization by Hal Brynteson.
