Blood and cellular flows
The most prominent example of a biofluid is blood. What makes blood flows so fascinating from a physical point of view is the coupling between the elastic behavior of the red blood cells and the viscous behavior of the surrounding plasma. This interaction creates a wealth of fascinating and often poorly understood phenomena.
A second example is the new and exciting technology of 3D bioprinting. Similar to an ink jet printer, a suspension of living cells is printed onto a substrate leading to hierarchically structured artificial tissue.
Here we use two different computational tools (Boundary Integral and Lattice-Boltzmann) to investigate cells in flows: Starting from the dynamics of a single red blood cell in a tube up to complex clustering phenomena of artificial microparticles in branching blood vessels.
