There exist various applications of transportation of slurries through pipelines all over the world. In the present study, the problem is formulated as a "transportation problem" to determine the pipe diameters and amounts of slurry to be transported from the demand (production) points to the processing (factory) points. The minimization of the cost consisting of the pipe and energy cost terms is considered as the objective function to determine the stated decision variables. Pipe cost is given as the function of pipe diameters and the energy cost is defined as function of pipe diameters and slurry amounts. Energy cost is obtained by using the relation that is previously determined after the experimental studies made for the magnetite ore. The optimization method used in the study is genetic algorithm method. A commercially available software written in C language is used and modified for the present study The proposed methodology to solve this nonlinear programming problem is applied to a transportation system and it is seen that the methodology made the complex, labor intensive equation solution process very convenient for the users.

Bonding efficiency of roller compacted concrete with different bedding mixes Özcan, Sinan; Yaman, İsmail Özgür; Department of Civil Engineering (2008) Roller Compacted Concrete (RCC) has rapidly evolved from a concept to a material and a process which is used throughout the world for faster and more economical construction of dams. Currently, there are more than 250 RCC dams, completed or under construction, in the world. On the other hand, currently, there are only two RCC dams completed (Suçatı and Cindere Dams) and two under construction (Beydağ and Çine Dam) in Turkey. RCC dams are constructed in a series of compacted layers usually 30 cm in thickness...
Physically based point snowmelt modeling and its distribution in euphrates basin Şensoy, Aynur; Şorman, Ali Ünal; Department of Civil Engineering (2005) Since snowmelt runoff is important in the mountainous parts of the world, substantial efforts have been made to develop snowmelt models with many different levels of complexity to simulate the processes at the ground, within the snow, and at the interface with the atmosphere. The land-atmosphere interactions and processing influencing heat transfer to and from a snowpack are largely variable and the conceptual representation of this temporal and spatial variability is difficult. A physically based, two laye...
Numerical simulation of unsteady flow in an oil pipeline under various hydraulic conditions Turan, Emrah; Bozkuş, Zafer; Department of Civil Engineering (2006) In the present study, transient flow analyses of a long oil pipeline are performed. Transient flow conditions are initiated by typical valve operations and pump trips that may be expected during operation of such pipelines. In order to simulate transient events an existing computer program called “Stoner Pipeline Simulator” has been used for a large number of hydraulic transient conditions. The program is based on the characteristics method solution of the governing water hammer equations. Locations that ma...
Impact of passanger comfort level on design of short-span composite steel i-girder high speed railroad bridges Şentürk, Tolga; Caner, Alp; Department of Civil Engineering (2009) In globalizing world, increase in demand for high speed rail travel requires comfortable ride over bridges while maintaining an economical design. These bridges either have composite steel I-girders, prestressed precast I or box girder superstructures. The span lengths can reach up to 40 meters. If frequency of wheel load pass at a point on bridge matches with one the critical frequencies of the structure, excessive vibration can developed both at the train and the bridge even if the structure is structural...
Cost estimation of trackworks of light rail and metro projects Öztürk, Erhan; Gündüz, Murat; Department of Civil Engineering (2009) The main objective of this work is to develop models using multivariable regression and artificial neural network approaches for cost estimation of the construction costs of trackworks of light rail transit and metro projects at the early stages of the construction process in Turkey. These two approaches were applied to a data set of 16 projects by using seventeen parameters available at the early design phase. According to the results of each method, regression analysis estimated the cost of testing sample...
