FLOWLab is super excited to announce the publication of our latest article titled "Microstructure Aware Modeling Of Biochemical Transport In Arterial Blood Clots" in the Journal of Biomechanics. This article illustrates our ongoing work on microstructure aware modeling of thrombotic phenomena in arterial hemodynamics. We extend our custom fictitious domain approach for mesoscale modeling of heterogeneous blood clots. Specifically, here we outline the presence and formation of space-time varying coherent structures around an arterial clot that regulates advective transport. Furthermore, the heterogeneous microstructure representation enables us to model diffusive intra-thrombus transport. Using some cycle-averaged long time simulations we identify trends in intra-thrombus transport, based on an extension of the fictitious domain approach to advection-diffusion equations. Please find the journal version of the article at: https://www.sciencedirect.com/science/article/pii/S0021929021004607. You can also download an author's preprint version from bioRxiv at the following link: https://www.biorxiv.org/content/10.1101/2021.01.25.428179v2. We welcome comments and discussions from the community! Thank you also to all the reviewers and editors who helped with this publication during these challenging times.

FLOWLab is super excited to announce the publication of our latest article titled "Computational investigation of blood flow and flow mediated transport in arterial thrombus neighborhood" in the journal Biomechanics and Modeling in Mechanobiology. The article illustrates our continued work in the area of thrombosis and thrombus biomechanics. Using a custom computational method, and parametric numerical investigations, we show how advection, diffusion, and permeation processes are regulated by the flow around the clot, clot microstructure, and status of artery wall leakage at the location of the clot.
