We at FLOWLab are pleased to share the publication of our latest article "A stabilized finite element technique for transport phenomena within and around immersed porous bodies in flow." in Physics of Fluids. You can find the article linked HERE. 
Key takeaways:
  • We demonstrate a stabilized algorithm that can robustly resolve sharp discontinuities at boundaries of immersed porous bodies in flow using local edge-based diffusion.
  • The formulation can handle arbitrarily space-time varying or moving porous domains in non-conforming/non-fitted discretizations.
  • The methodology is reproducibly implemented for the broader community through FLOWLab's FLATiron Toolkit (available on GitHub).
Immersed porous media are abundant in biofluids. A major example in physiological settings involves blood clots - where flow and flow-mediated transport within and around heterogeneous clot aggregates remains extremely challenging to resolve in real human vascular networks. Our methodology is a step towards addressing this challenge.
The work was led by Chayut Teeraratkul, with support from our collaborators Timothy Stalker and Maurizio Tomaiuolo. If you are interested in this work, in our ongoing research portfolio on blood clots, and on FLATiron Toolkit - please DM/email me, and we can chat more!
