Heat transport by fluid flows with prescribed velocity fields
Abstract:
We study the problem of heat transport by fluid flows with prescribed velocity fields. The advection-diffusion equation in two dimensions is solved for two velocity fields: (i). a circulation and (ii). a shear flow. These two flows focus separately on the two dominant features of the mean large-scale flow observed in turbulent convection experiments. We find that the Nusselt number, which measures the heat transport, scales respectively for the two velocity fields.
