1. 1. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

   University essay from KTH/Teknisk mekanik

   Author : Simon Garpenquist; [2023]
   Keywords : Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

   Abstract : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. READ MORE

3. 2. Turbulent Duct Flow with Polymers

   University essay from KTH/Mekanik

   Author : Armin Shahmardi; [2018]
   Keywords : ;

   Abstract : Direct numerical simulation of the turbulent flow in a square duct with polymers has been performed and the results have been compared with the laboratory experiments done at KTH Mechanical engineering department. The polymer suspension is simulated with the FENE-P model, and the numerical results are used to elucidate the mechanism that provides drag reduction and the effect of polymers on the secondary motion which is typical of the turbulent flow in ducts.

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

   University essay from KTH/Mekanik

   Author : Faranggis Bagheri; [2010]
   Keywords : polymer turbulent Lyapunov exponent;

   Abstract : 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. READ MORE
