1. 11. CFD Modelling of Direct Gas Injection Using a Lagrangian Particle Tracking Approach

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Mathias Vångö; [2015]
   Nyckelord :Lagrangian Particle Tracking; Gas injection; CFD; Jets; OpenFOAM; LPT; Technology and Engineering;

   Sammanfattning : CFD simulations of direct gas injection, especially in large dual-fuel engines, can be expensive both regarding time and computational power. The nozzle area needs to be resolved with a fine mesh to capture all phenomena and for a full engine model this results in a large amount of cells. LÄS MER

3. 12. Numerical Study of Polymers in Turbulent Channel Flow

   Master-uppsats, KTH/Mekanik

   Författare :Faranggis Bagheri; [2010]
   Nyckelord :polymer turbulent Lyapunov exponent;

   Sammanfattning : The phenomenon of drag reduction by polymers in turbulent flow has beenstudied over the last 60 years. New insight have been recently gained by meansof numerical simulation of dilute polymer solution at moderate values of theturbulent Reynolds number and elasticity. LÄS MER
