Extensible membranes in inviscid flow: aerodynamics and singular limits
Yu Jun Loo, Silas Alben
We develop a two-dimensional inviscid model for extensible membranes with continuous vortex shedding from both edges, coupled to a weak spectral Galerkin discretization of the memb…
Comparison of inviscid and viscous vortex shedding from translating and rotating plates
Yu Jun Loo, Silas Alben
We compare an inviscid vortex sheet model with continuous leading-edge shedding with direct Navier-Stokes simulations over a wide range of unsteady plate motions at moderate Reynol…
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…
Wavy optimal flows for heat transfer in channels
Shivani Prabala, Silas Alben
We compute incompressible two-dimensional fluid flows that maximize the rate of heat transfer from the walls of a straight channel given a specified flow input power , wher…
Falling plates with leading-edge vortex shedding
Yu Jun Loo, Silas Alben
We develop a new numerical method for thin plates falling in inviscid fluid that allows for leading-edge vortex shedding. The inclusion of leading-edge shedding restores physical d…
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…
