Energy conservation in incompressible convection

ORAL

Abstract

In classic Rayleigh-B\'enard convection, energy is not conserved. Here we study a set of incompressible equations that do conserve energy when thermal diffusion is present. Using the Dedalus pseudospectral framework, we study heat transport by convection in simulations of incompressible but energy-conserving equations. We compare heat transport properties to classic Rayleigh-B\'enard convection.
