Development of a high-order navier-stokes solver for aeroacoustic predictions of wind turbine blade sections
Yalçın, Özgür; Özyörük, Yusuf; Department of Aerospace Engineering (2015)
Increased interest in renewable energy in the world has lead to research on wind turbines at a great pace. However, these turbines have come with a noise problem. The noise source of wind turbines is primarily aerodynamic noise highly related to complex, three dimensional, unsteady flow fields around them. Therefore, determination of these sources requires successful, accurate, turbulent flow solutions. In addition, because acoustic waves are non-dispersive and non-dissipative, such solutions must be carrie...
Development of a shell finite element for large deformation analysis of laminated composites
Yıldız, Tuba; Darendeliler, Haluk; Department of Mechanical Engineering (2008)
The objective of the present work is to investigate the behavior of laminated fiber -reinforced polymer matrix composite shell structures under bending load with the help of a modified finite element computer code which was previously developed for the analysis of pseudo-layered single material shells. The laminates are assumed to be orthotropic and the formulation is adapted to first order shear deformation theory. The aim is to determine the large deformation characteristics numerically, and to predict th...
Development of a pressure-based solver for both incompressible and compressible flows
Denk, Kerem; Sert, Cüneyt; Department of Mechanical Engineering (2007)
The aim of this study is to develop a two-dimensional pressure-based Navier-Stokes solver for incompressible/compressible flows. Main variables are Cartesian velocity components, pressure and temperature while density is linked to pressure via equation of state. Modified SIMPLE algorithm is used to achieve pressure-velocity coupling. Finite Volume discretisation is performed on non-orthogonal and boundary-fitted grids. Collocated variable arrangement is preferred because of its advantage on staggered arrang...
