This thesis is intended to study the fluid behaviour with a new approach through the particle simulation technique. The fluid is considered to be under static conditions, and the activity of fluid particles is simulated. The method in the approach is mathematically exact. Instantaneous velocities are calculated with simple algebraic equations. Hence high efficiency in CPU time is achieved. In order to validate the method, the probability density function of the Maxwell-Boltzmann speed distribution and the pressure are calculated and compared with the theoretical values. It is shown that the difference between the theoretical calculations and the present method, providing the associated speeds of the Maxwell-Boltzmann distribution, is less than 3% for different system temperatures. The pressure values are also reasonably close to each other.

Applications of a particle simulation approach Kabakcı, İsmail; Çöker, Demirkan; Department of Aerospace Engineering (2019) The thesis is intended to utilize a particle simulation approach, introduced for simple particles, for engineering problems in order to study and understand fluid behavior at molecular level. First, an improvement in force potential estimation is proposed for the original method, which offers notable accuracy increase in simulations in terms of determination of position and momentum trajectories. Afterwards, the improved method is applied to heat diffusion and unidirectional fluid flow simulations. Within t...
Application of spring analogy mesh deformation technique in airfoil design optimization Yang, Yosheph; Özgen, Serkan; Department of Aerospace Engineering (2015) In this thesis, an airfoil design optimization with Computational Fluid Dynamics (CFD) analysis combined with mesh deformation method is elaborated in detail. The mesh deformation technique is conducted based on spring analogy method. Several improvements and modifications are addressed during the implementation of this method. These enhancements are made so that good quality of the mesh can still be maintained and robustness of the solution can be achieved. The capability of mesh deformation is verified by...
Application of fully implicit coupled method for 2D incompressible flows on unstructured grids Zengin, Şeyda; Tarman, Işık Hakan; Department of Engineering Sciences (2012) In the subject of Computational Fluid Dynamics (CFD), there seems to be small number of important progress in the pressure-based methods for several decades. Recent studies on the implicit coupled algorithms for pressure-based methods have brought a new insight. This method seems to provide a huge reduction in the solution times over segregated methods. Fully implicit coupled algorithm for pressure-based methods is very new subject with only few papers in literature. One of the most important work in this a...
Implicit lattice boltzmann method for laminar/turbulent flows Çevik, Fatih; Albayrak, Kahraman; Department of Mechanical Engineering (2016) Lattice Boltzmann Method is an alternative computational method for fluid physics problems. The development of the method started in the late 1980s and early 1990s. Various numerical schemes like stream and collide, finite difference, finite element and finite volume schemes are used to solve the discrete Lattice Boltzmann Equation. Almost all of the numerical schemes in the literature are explicit schemes to exploit the natural features of the discrete Lattice Boltzmann Equation like parallelism and easy c...
Vortex generator design for subsonic inlets Nasuhbeyoğlu, Batuhan; Albayrak, Kahraman; Department of Mechanical Engineering (2014) In this thesis, numerical investigation of the benefits of vortex generators control on the performance of S-shaped inlets has been performed. This study is divided into two main parts. In the first part, a diffusive S-shaped inlet is examined and the numerical analyses results are compared with the experimental results. Three-dimensional Navier-Stokes equations are solved and three different turbulence models which are Realizable k-ε, Standard k-ω, and Spalart-Allmaras methods are used. Distortion coeffici...
