  1. 1. Analyzing arterial blood flow by simulation of bifurcation trees

    Master-uppsats, Linköpings universitet/Matematik och tillämpad matematik

    Författare :Johan Ottosson; [2019]
    Nyckelord :Arterial blood flow; Blood flow modelling; bifurcation tree; simulation; fixed-point iteration;

    Sammanfattning : The flow of blood in the human body is a very important component in un-derstanding a number of different ailments such as atherosclerosis and a falseaneurysm. In this thesis, we have utilized Poiseuille’s solution to Navier-Stokesequations with a Newtonian, incompressible fluid flowing laminar with zero ac-celeration in a pipe with non-flexible walls in order to study blood flow in anarterial tree.

    Sammanfattning : It is known that there are many cardiovascular diseases caused by the alterations in the blood vessels, that affect most of the world population. The knowledge of the mechanobiological behavior of blood vessels is used for understanding how cardiovascular diseases could affect the human body. LÄS MER

  4. 3. Pressure Estimation in the Systemic Arteries Using a Transfer Function

    Magister-uppsats, Mekanik; Tekniska högskolan

    Författare :Carl-Johan Thore; [2007]
    Nyckelord :Pressure Estimation; Pulse Pressure; Wave Propagation; Cardiovascular System; Arteries;

    Sammanfattning : The aim of this thesis is to develop and study a method for estimation of the pulse pressure in centrally located arteries. Obtaining the central pulse pressure is desirable for several reasons. For example, the central pulse pressure can be used to assess aortic stiffness, which in turn is an important predictor of cardiovascular mortality. LÄS MER
