  2. 1. Interacting particles and droplets at low Reynolds numbers

    Author : Lisa Prahl; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; VOS; VOF; Multiphase flow; Interaction; Particles; Droplets; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma;

    Abstract : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. READ MORE

  4. 2. 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

  5. 3. Computational modelling of blood flow in medical assist devices

    Author : Francesco Fiusco; Lisa Prahl Wittberg; Lars Mikael Broman; Anders Dahlkild; David Ku; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational fluid dynamics; haemodynamics; platelet activation; thrombogenicity; haemolysis; extracorporeal membrane oxygenation; sensitivity; Teknisk mekanik; Engineering Mechanics;

    Abstract : Extracorporeal membrane oxygenation (ECMO) is a life-saving support treat-ment in case of pulmonary and/or cardiac failure. An artificial extracorporealcircuit is used to offload the function of lungs and/or heart. READ MORE

  6. 4. Hemodynamics of artificial devices used in extracorporeal life support

    Author : Francesco Fiusco; Lisa Prahl Wittberg; Katharine Fraser; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computational fluid dynamics; hemorheology; platelet activation; thrombogenicity; extracorporeal membrane oxygenation; hemodynamics; Engineering Mechanics; Teknisk mekanik;

    Abstract : Extracorporeal Membrane Oxygenation (ECMO) is a life-saving therapy usedfor support in critical heart and/or lung failure. Patient’s blood is pumped viaan artificial lung for oxygenation outside of the body. The circuit is composedof a blood pump, cannulae for drainage and reinfusion, a membrane lung,tubing and connectors. READ MORE

  7. 5. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

    Author : Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

    Abstract : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). READ MORE
