TURBULENT BOUNDARY-LAYER AND THE EFFECT OF CRITICAL ROUGHNESS REYNOLDS-NUMBERS ON THE RECOVERY LENGTH BEHIND AN ISOLATED SPHERICAL ROUGHNESS ELEMENT UNDER VARIABLE PRESSURE-GRADIENT
Albayrak, Kahraman (1990-03-01)
The transition characteristics and the boundary layer development behind an isolated spherical roughness element were investigated in an open-circuit, suction-type wind tunnel. The experiments were performed upon a smooth aluminiuim flat plate placed in the test section of the tunnel. The desired pressure gradient was obtained by means a false roof placed in the test section. In this article, emphasis is given to the recovery length of the turbulent boundary layer behind an isolated spherical roughness ele...
Performance improvement of a 3d reconstruction algorithm using single camera images
Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005)
In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...
Nanoscale Thermal Transport in Single, Bilayer Graphene, and Graphite
Gholivand, Hamed; Donmezer, Nazli (2016-10-12)
In this study, ab-initio calculations were performed to obtain phonon dispersions of single, bilayer graphene, and graphite structures. Using these dispersions single mode relaxation times, thermal conductivities, and mean free paths (MFPs) have been calculated. Finally, calculated variables were used to understand the effects of additional layers to thermophysical properties, phonon mode contributions to thermal conductivity, and the limits for ballistic-diffusive heat transfer of single, bilayer graphene,...
Heat Transfer Simulation of Rarefied Laminar Flow past a Circular Cylinder
Çelenligil, Mehmet Cevdet (2016-07-15)
Direct simulation Monte Carlo calculations are performed to study the heat transfer in laminar, rarefied flows past a circular cylinder. Results are obtained for flows with Knudsen numbers of 0.02 and 0.2; Mach numbers of 0.102 and 0.4, and also several cylinder temperatures are considered. Calculations show that these flows are attached except for the one with a Knudsen number of 0.02 and a Mach number of 0.4 in which separation occurs in the wake of the cylinder. Results are little affected by the changes...
Shear strength behavior of granular fill-clayey soil interfaces and improvement with dowels
Öztürk, Şevki; Ergun, Mehmet Ufuk; Department of Civil Engineering (2015)
Shear failures of interfaces between granular material and clay are frequently encountered in engineering practice. In earthfill dams, road embankments and spoil piles in mining operations, granular materials are placed on clay, and shear failures and/or large movements are observed along interfaces. When dealing with this type of a problem selecting representative shear strength parameters is difficult. Furthermore in the literature no accepted procedure is available to select these parameters. This study ...
