  2. 1. Turbulent Flow in Constricted Blood Vessels : Quantification of Wall Shear Stress Using Large Eddy Simulation

    Author : Roland Gårdhagen; Matts Karlsson; Toste Länne; Leif Rune Hellevik; Linköpings universitet; []
    Keywords : ;

    Abstract : The genesis of atherosclerosis has previously been shown to be affected by the frictional load from the blood on the vessel wall, called the wall shear stress (WSS). Assessment of WSS can therefore provide important information for diagnoses, intervention planning, and follow‐up. READ MORE

    Abstract : In recent years, applications of confluent jets for design of ventilation supply devices have been widely studied. Similarly, numerous studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. READ MORE

  5. 3. Important Factors for Accurate Scale-Resolving Simulations of Automotive Aerodynamics

    Author : Petter Ekman; Matts Karlsson; Torbjörn Virdung; Roland Gårdhagen; Adrian Gaylard; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Road transports are responsible for almost 18 % of the greenhouse gas emission in Europe and are today the leading cause of air pollution in cities. Aerodynamic resistance has a significant effect on fuel consumption and hence the emission of vehicles. READ MORE
