Comparison of dispersive and non-dispersive numarical long wave models and harbor agitation
Özbay, Ali; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2012)
In this study, the evolution of the numerical water wave models with the theoretical background and the governing equations are briefly discussed and a numerical model MIKE21 BW which can be applied to wave problems in nearshore zone is presented. The numerical model is based on the numerical solution of the Boussinesq type equations formulated on time domain. Nonlinearity and frequency dispersion is included in the model. In order to make comparison between the results of nonlinear shallow water equations ...
Comparison of turbulence model and wall function couplings for simulating scour
Şentürk, Barış Ufuk; Baykal, Cüneyt; Department of Civil Engineering (2022-1-19)
In this study, the scouring of bed material at the rear side of a rubble mound coastal revetment due to the overtopping of solitary-like waves is numerically studied using a coupled hydrodynamic and morphological computational fluid dynamics model. The major purpose of this thesis study is to investigate the performances of different turbulence model and wall function couplings on the hydrodynamic and morphological results. In the first part of this study, hydrodynamic simulations are performed, and the res...
Comparison of parametric models for conceptual duration estimation of building projects
Helvacı, Aziz; Sönmez, Rifat; Department of Civil Engineering (2008)
Estimation of construction durations is a very crucial part of project planning, as several key decisions are based on the estimated durations. In general, construction durations are estimated by using planning and scheduling techniques such as Gannt or bar chart, the Critical Path Method (CPM), and the Program Evaluation and Review Technique (PERT). However, these techniques usually require detailed design information for estimation of activity durations and determination of the sequencing of the activitie...
Comparison of Fine Grained and Coarse Grained Parallel Models in Particle Swarm Optimization Algorithm
Baştürk, Alper; Akay, Rüştü; Kalınlı, Adem (2011-11-23)
Many optimization problems are generally complex and required to be solved in parallel architectures due to theircomputational costs. The main issue about the parallelism is that the parallel architectures may affect the performancebecause the original models are constructed based upon the sequential architectures. Therefore, the parallelizationapproaches should consider the efficiency in addition to reducing computational cost. The objective of this paper is two-fold.First goal is presenting a parallelizat...
