• W4309332181 abstract "Internally heated convection involves the transfer of heat by fluid motion between a distribution of sources and sinks. Focusing on the balanced case where the total heat added by the sources matches the heat taken away by the sinks, we obtain emph{a priori} bounds on the minimum mean thermal dissipation $langle |nabla T|^2rangle$ as a measure of the inefficiency of transport. In the advective limit, our bounds scale with the inverse mean kinetic energy of the flow. The constant in this scaling law depends on the source--sink distribution, as we explain both in a pair of examples involving oscillatory or concentrated heating and cooling, and via a general asymptotic variational principle for optimizing transport. Key to our analysis is the solution of a pure advection equation, which we do to find examples of extreme heat transfer by cellular and `pinching' flows. When the flow obeys a momentum equation, our bound is re-expressed in terms of a flux-based Rayleigh number $Ra$ yielding $langle |nabla T|^2ranglegeq CRa^{-alpha}$. The power $alpha$ is $0, 2/3$ or $1$ depending on the arrangement of the sources and sinks relative to gravity." @default.
