3. 2. Stenotic Flows: Direct Numerical Simulation,Stability and Sensitivity to Asymmetric ShapeVariations

   Master-uppsats, KTH/Mekanik

   Författare :John GW Samuelsson; [2014]
   Nyckelord :;

   Sammanfattning : Flow through a sinuous stenosis with varying degrees of shape asymmetry andat Reynolds number ranging from 250 up to 800 is investigated using direct numericalsimulation (DNS), global linear stability analysis and sensitivity analysis.The shape asymmetry consists of an offset of the stenosis throat, quantifiedas the eccentricity parameter, E.
