Explicit interface tracking of moving Red Blood Cells in finite volume mesh

摘要

Advances in medical science have seen a growth in the virtual modelling of rheological-blood systems. Current studies of Theological systems are predominantly based on simplified empirical characterisations of non-Newtonian fluids . To gain a more in-depth understanding of these processes, explicit modelling of red blood cells, their movement, collisions and fluid dynamic interactions are necessary. Here, we seek to explicitly model the bi-concave disc shape of red blood cells and track their movement against the background of non-moving finite volume mesh. This was achieved using an interface tracking method developed in-house in Fortran95. Explicit Lagrangian tracking of blood cells carries the potential for finite element analysis (FEA) simulations of cell structures and the modelling of fluid-structure interactions.
