1. 1. Hybrid Grid Generation for Viscous Flow Computations Around Complex Geometries

   Författare :Lars Tysell; Laszlo Fuchs; Nigel P. Weatherill; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; grid generation; unstructured grids; hybrid grids; surface grids; three-dimensional grids; adaptive grids; moving grids; grid quality; accuracy; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : A set of algorithms building a program package for the generation of twoandthree-dimensional unstructured/hybrid grids around complex geometrieshas been developed. The unstructured part of the grid generator is based on the advancing frontalgorithm. LÄS MER

3. 2. Adaptive Mesh Refinement and Simulations of Unsteady Delta-Wing Aerodynamics

   Författare :Yann Le Moigne; KTH; []
   Nyckelord :delta wing; high angle of attack; vortex; pitching; mesh refinement; UCAV; vortex sensor; tensor ofvelocity gradients;

   Sammanfattning : This thesis deals with Computational Fluid Dynamics (CFD)simulations of the flow around delta wings at high angles ofattack. These triangular wings, mainly used in militaryaircraft designs, experience the formation of two vortices ontheir lee-side at large angles of attack. LÄS MER
