15.00-16.00: Keynote talk from Dr. Timm Krüger, "“Cellular blood flow modelling in the human body - challenges and outlook”

Speaker Bio: Timm Krüger is Reader in Chemical Engineering in the School of Engineering at the University of Edinburgh. He specialises in Lattice-Boltzmann modelling and simulation of complex fluids, for example: emulsions, suspensions of deformable particles or red blood cells in blood vessels and microfluidic devices.

Keynote Talk Abstract: There has been a recent increase in modelling of blood flow in disease, such as malaria, sickle cell anemia or cancer. Blood flow modelling becomes particularly challenging at the scale of arterioles and capillaries where the diameters of blood vessels and red blood cells (RBCs) are similar. In these cases, computationally expensive cell-based models are still required to uncover suspension flow effects and predict cell distribution and tissue oxygenation. Deformable RBCs are typically modelled as hyperelastic or viscoelastic capsule-vesicle hybrids that are fully coupled to the ambient fluid flow and allow to capture the cell deformation and dynamics on the micron level. In order to enable more quantitative predictions in larger blood vessel networks (e.g. on the organ level), more efficient reduced models are required. I will give a short overview of existing microscopic blood flow models and ongoing activities to develop effective blood flow models applicable to larger scales.
