On the nature of the boundary resonance error in numerical homogenization and its reduction
Sean P. Carney, Milica Dussinger, Bjorn Engquist
Numerical homogenization of multiscale equations typically requires taking an average of the solution to a microscale problem. Both the boundary conditions and domain size of the m…

Steric effects in induced-charge electro-osmosis for strong electric fields
J. Galen Wang, Daniel R. Ladiges, Ishan Srivastava +4
We study the role of steric effects on the induced-charge electro-osmosis (ICEO) phenomenon using a recently developed mesoscale fluid model. A hybrid Eulerian-Lagrangian method is…
