1. 1. Simulations of a self-stabilizing fully submerged hydrofoil

   University essay from KTH/Matematik (Avd.)

   Author : Henry Jacobson; [2023]
   Keywords : Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

   Abstract : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. READ MORE

3. 2. Longitudinal Flight Mechanics of Paraglider Systems

   University essay from KTH/Flygdynamik

   Author : Rene Falquier; [2019]
   Keywords : ;

   Abstract : This project outlines a cost-effective numerical simulation method for the analysis of the longitudinal mechanics of paraglider systems. It is built on static stability methods for the analyses of low subsonic aircraft, non-linear lifting line methods for aerodynamic parameterization, and frequency domain analysis methods derived from system theory.

4. 3. Study of tip clearance flows

   University essay from KTH/Flygdynamik

   Author : Camille Fournis; [2018]
   Keywords : turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

   Abstract : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. READ MORE
