  4. 2. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Author : Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Abstract : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. READ MORE

  5. 3. Numerical Simulation of Unsteady Flows of Physiological Relevance

    Author : Philip Evegren; Institutionen för energivetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wall shear stress; Biofluid mechanics; Pulsatile flow; Atherosclerosis; Flow in bifurcations;

    Abstract : Pulsatile flows in geometries of physiological relevance have been investigated. Atherosclerotic plaques are (initiated) near junctions and bifurcations in larger arteries. The flow in these regions is characterized by flow separation and unsteadiness, which indicates that local flow conditions contribute to atherogenesis. READ MORE

  6. 4. Blood flow and cell transport in arteries and medical assist devices

    Author : Niclas Berg; Lisa Prahl Wittberg; Laszlo Fuchs; Mihai Mihaescu; Alessandro Veneziani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodynamics; CFD; Artherosclerosis; Thrombosis; Platelet activation; Hemorheology; Platelet margination; Technology and Health; Teknik och hälsa;

    Abstract : The cardiovascular system is responsible for transport of nutrients, oxygen, as well as the cells and molecules making up the immune system. Through the hemostatic system, the body maintains the integrity of the blood vessels, and prevents bleeding. READ MORE

  7. 5. The influence of inertia on the rotational dynamics of spheroidal particles suspended in shear flow

    Author : Tomas Rosén; Fredrik Lundell; Minh Do-Quang; Johan Revstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-spherical particles; non-linear dynamics; Engineering Mechanics; Teknisk mekanik;

    Abstract : Dispersed particle flows occur in many industrial, biological and geophysical applications. The knowledge of how these flow behave can for example lead to improved material processes, better predictions of vascular diseases or more accurate climate models. READ MORE
