Enhancing wall-to-wall heat transport with unsteady flow perturbations
Silas Alben, Xiaojia Wang, Nicole Vuong
We determine unsteady flow perturbations that are optimal for enhancing the rate of heat transfer between hot and cold walls (i.e. the Nusselt number Nu), under the constraint of f…

How vortices enhance heat transfer from an oscillating plate
Xiaojia Wang, Silas Alben
Oscillations of a heated solid surface in an oncoming fluid flow can increase heat transfer from the solid to the fluid. Previous studies have investigated the resulting heat trans…
