Interaction of non-Newtonian fluids with deformable structures in microscale biological processes

In FY2022, we developed the tools and laid the foundations for making the key in-silico experiments. Initially, we developed the algorithm and implemented it in the in-house parallel FE code. We performed strict mesh and time-step refinement convergence tests for VFSI past a single deformable cylinder. We found that the method exhibits second-order accuracy in space and time. We also validated the numerical results with microfluidic experiments of viscoelastic flow past two cantilevered cylinders; semi-quantitative agreement was achieved. All the results are summarized in a manuscript that will be submitted in the journal "Computer Methods in Applied Mechanics and Engineering".
