SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Next Monday\, 26th June at 11:30\, we will have the pleasure to listen to Christian Wagner (Saarland University) who will discuss his recent work on blood flow dynamics.Gulliver library\, or remotely at the zoom link \nRemote connection detailshttps://us02web.zoom.us/j/81716487543?pwd=c1IrZWYzTEhvaFFBZmtIK3Z6SmZRUT09ID de réunion : 817 1648 7543Code secret : 712938\n**********************************\nThe physics of blood flow\n\nBlood is a complex fluid composed of red and white cells suspended in a protein solution called plasma. At low shear rates\, red blood cells form aggregates\, which are broken up at high shear rates\, resulting in pronounced shear thinning.  Nevertheless\, in most medical simulations\, blood is treated as a Newtonian fluid comparable to water. However\, thanks to recent advances in numerical simulation techniques and experimental methods\, it is now possible to describe the flow of blood in terms of the physical properties of individual cells. Red blood cells can pass through capillaries smaller than their own diameter\, thanks to their high deformability. This implies a strong interaction between fluid and structure that makes simulations costly and realistic simulations are limited to a few thousand cells. We will present in vitro\, in vivo and in silico results of cells in different flow geometries. By directly comparing the observed shapes\, we can estimate the mechanical constants of the cells. However\, in many pathological situations\, the cell properties are highly altered\, and we have used our artificial intelligence-based recognition algorithm to develop a tool that can assess\, for example\, the quality of blood products.\nFinally\, we will show that a well-established nonspecific diagnostic test for inflammation\, the erythrocyte sedimentation rate (ESR)\, can be physically described as a new class of fragile gel made of very soft\, deformable objects. We find that sedimentation rate has a surprising functional relationship with interaction strength and propose new evaluation criteria for this test.
