This paper presents the design, computational analysis and experimental study of passive device configurations which utilized in the Ankara Wind Tunnel to simulate the atmospheric boundary layer within the test section. The study here is part of a joint project between the Aerospace and Civil Engineering Departments at Middle East Technical University, which involves testing of high-rise building models in the Ankara Wind Tunnel. The design consists of spires and rows of cubical surface roughness elements at the inlet. The preliminary computational analysis shows that the current design may provide the desired boundary layer thickness at about 4.0 m downstream of the test section inlet, which leaves enough room for the building models to be placed in the test section. This study also helps obtaining a preliminary understanding of the boundary layer development and reducing the tunnel operation time and cost during the actual experimentation phase. At the end, experimental results show acceptable results of this study.

Design of a traverse system for the characterization of a large-scale wind tunnel Ulu, Tunahan; Perçin, Mustafa; Department of Aerospace Engineering (2022-9) This study presents the design and simulations of a traverse system and preliminary characterization measurements of the RÜZGEM large-scale wind tunnel. In the first phase of the study, the traverse system was simulated aerodynamically using computational fluid dynamics (CFD) tools. The effects of the rectangular, whole profile and partial profile traverse mechanisms on the measurements were examined. The probe lengths were studied in detail to determine the most suitable length. According to the simulation...
Flutter characteristics of plate like structures Dalmış, Mevlüt Burak; Yazıcıoğlu, Yiğit; Durak, Burak; Department of Mechanical Engineering (2014) In this study, flutter characteristics of plate like structures in incompressible flow are investigated by comparing the results of commercial flutter analysis program ZAERO© with wind tunnel tests conducted in Ankara Wind Tunnel (ART). Firstly, a rectangular polycarbonate (PC) plate, 5x125x1000 mm in dimensions, is investigated. In this case, analysis and test results are in good agreement with each other. Second test item is a 1/10 scaled F-16 wing like PC plate. In this case, the plate is capable of carr...
Computational fluid dynamics modelling of store separation using grid method Demir, Görkem; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2017) In this study, two different wind tunnel techniques, captive trajectory and the grid surveying method, were implemented to computational fluid dynamics (CFD) and used to calculate the trajectory of a store. The main purpose of this thesis is to demonsrate that grid method is an alternative method to those already used as it provides flexibility to store separation problems and can be used during the design process. EGLIN test geometry was used to validate the analyses results because it provided existing wi...
Dynamic modelling and simulation of a wind turbine Altuğ, Ayşe Hazal; Yavrucuk, İlkay; Department of Aerospace Engineering (2015) In this thesis, a dynamic model for a horizontal axis wind turbine is developed for an upwind configuration using the MATLAB/Simulink environment. Blade Element Momentum Theory is used to model the rotor. It is assumed that the rotor blades are rigid and wind speed is uniform. Aerodynamic and gravitational forces are calculated as distributed loads. Verification of the model is done by using the LMS Samtech, Samcef for Wind Turbines software. Aerodynamic properties of the blades, sectional loads and moments...
Optimizing Single-Span Steel Truss Bridges with Simulated Annealing Hasançebi, Oğuzhan (2010-11-01) This study presents applications of a simulated annealing integrated solution algorithm to the optimum design of single-span steel truss bridges subjected to gravity loadings. In the optimum design process of a bridge the members are sized simultaneously as the coordinates of the upper chord nodes are determined such that the least design weight is attained for the structure. The design constraints and limitations are imposed in accordance with serviceability and strength provisions of ASD-AISC (Allowable S...
