Hello, dear Nekers,<br>
<br>
Here I would like to draw your attention to our recently published
paper '<a moz-do-not-send="true"
href="http://pubs.rsc.org/en/content/articlelanding/2014/sm/c4sm01097c#%21divAbstract">http://pubs.rsc.org/en/content/articlelanding/2014/sm/c4sm01097c#!divAbstract</a>'.<br>
We perform 3D direct numerical simulations by NEK5000 to help the
design of a micro-fluidic device capable of<br>
differentiating and sorting biological cells based on their
deformability. As far as we know, this is the first attempt of using
NEK as a<br>
platform to fully resolve the fluid-structure interaction at low
Reynolds number. Indeed, we use an accelerated <br>
boundary integral method (BIM) to solve the Stokes flow, one part of
the solution is from the Stokes solver of NEK5000, and another<br>
from traditional boundary integral computations. As we employ a
spherical-harmonics-based spectral method to <br>
interpretate the surface of the cell, the whole numerical framework
is of almost spectral accuracy (not exactly due to BIM); <br>
as well as near the immersed interface. For traditional immersed
boundary method or lattice Boltzmann method, the accuracy<br>
near the interface is normally around first to second order. Of
course, we then restrict our simulations in the Stokes regime.<br>
Our manuscript regarding the whole implementation is not published
yet, but is accessible as included in my Phd thesis, page 163<br>

I recently obtained my <br>
Phd degree with Prof. Luca Brandt at KTH Mechanics.<br>
