In this study, Computational Fluid Dynamics simulations of flow around thick have been performed. Thick airfoils are generally preferred in wind turbine blades for structural and aerodynamic performances. High Reynolds flows around thick airfoils are one of the challenging problems in wind turbine blade design due to turbulent, separated and complex flow field characteristics. In the CFD analyses, both 2-D RANS simulation approach on structured computational grids is considered. Grid sensitivity study is also performed and presented in this paper.

Elastic Response of Heat Generating Rod at a Variable Generating Rate
Eraslan, Ahmet Nedim; Varlı, Ekin (2014-09-28)
The aim of this study is to develop a computational model to analyze thermally induced stress and deformation in a heat generating solid rod. The rod is initially at zero temperature, but for times greater than zero heat is generated internally at both space and time dependent rate. As the rod is heated up slowly an uncoupled solution is realized. The heat conduction equation with a variable generation rate is solved by a finite element collocation method. Two different generation rates are handled. The num...
Numerical simulation of fluid flow and heat transfer in a trapezoidal microchannel with COMSOL multiphysics: A case study
Turgay, Metin Bilgehan; Güvenç Yazıcıoğlu, Almıla (2018-01-01)
In this study, fluid flow and heat transfer in a trapezoidal microchannel are numerically investigated. For this purpose, a reference study with experimental and numerical solutions is adopted from the literature and solved with COMSOL multiphysics. Good agreement with the results of the reference work is obtained. In addition, effects of stabilization methods and element discretization options that are offered by the program on the results are investigated and discussed with examples. In addition, two diff...
Numerical modelling of wave-structure interaction problems through cfd methods
Güler, Hasan Gökhan; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2020)
The major focus of this study is the computational fluid dynamics (CFD) modelling of wave-structure interaction problems. In the first part of this study, the performance of Haydarpaşa Breakwater under tsunami attack is assessed both experimentally and numerically. It is concluded that the major failure mechanism of this breakwater is the sliding of the crown-wall, and the stability of the stones located at the harbour side is also significant. Design recommendations are given based on the stability of the ...
Deep Learning Based Speed Up of Fluid Dynamics Solvers
Acar, Deniz Alper; Uzol, Oğuz; Department of Aerospace Engineering (2022-9-8)
In this thesis, two distinct deep learning-based methods for the speed-up of fluid dynamics solvers are proposed. The first method called Parametric Encoded Physics informed neural network (PEPINN), is utilized to solve transient fluid dynamics problems. PEPINN is an alternative to the Physics informed neural networks (PINN) and is based on the parametric encoding of the problem domain. In PEPINN the automatic differentiation for calculation of the problem residual is replaced with finite difference kernel...
Numerical investigation of characteristics of pitch and roll damping coefficients for missile models
Kayabaşı, İskander; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2012)
In this thesis the characteristics of pitch and roll damping coefficients of missile models are investigated by using Computational Fluid Dynamics (CFD) techniques. Experimental data of NACA0012 airfoil, Basic Finner (BF) and Modified Basic Finner (MBF) models are used for validation and verification studies. Numerical computations are performed from subsonic to supersonic flow regimes. Grid refinement and turbulence model selection studies are conducted before starting the dynamic motion simulations. Numer...
