Coaxial jet flows have a considerable practical application area as water jet pumps. Efficiency of such systems is affected by complex turbulence mechanisms and large-scale vortex structures formed in the mixing regions. An experimental setup is constructed to estimate the momentum exchange rates and mixing of the two jet flows from the coaxial pipes. Pressure distributions along the mixing pipe wall are measured for different flow ratios of the jets. In addition to present experiments, numerical data of two experimental studies from the literature are considered as test cases. Numerical solutions for the test cases are obtained using FLUENT. Experimental and numerical results are compared and adequacy of FLUENT solution is illustrated.

Comprehensive modelling of gas condensate relative permeability and its influence on field performance Çalışgan, Hüseyin; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2005) The productivity of most gas condensate wells is reduced significantly due to condensate banking when the bottom hole pressure falls below the dew point. The liquid drop-out in these very high rate gas wells may lead to low recovery problems. The most important parameter for determining condensate well productivity is the effective gas permeability in the near wellbore region, where very high velocities can occur. An understanding of the characteristics of the high-velocity gas-condensate flow and relative ...
Optimum design of slurry pipelines Yıldız, Burhan; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2009) 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 funct...
Energy dissipation by vertically placed screens Bozkuş, Zafer; GER, A. Metin (Canadian Science Publishing, 2007-04-01) Screens can be utilized efficiently for dissipating energy of water. In this study, water flowing beneath a gate is used to simulate the flow downstream of a small hydraulic structure, and vertically placed screens are used as an alternative tool for energy dissipation. Investigations are conducted using a series of experiments. The porosity, thickness, and location of the screens are the major parameters together with the Froude number of the upstream flow. The experiments cover a range of supercritical Fr...
Lateral buckling of overhanging crane trolley monorails Ozdemir, Kerem Murat; Topkaya, Cem (Elsevier BV, 2006-07-01) Lateral torsional buckling should be taken into account during the design of overhanging steel beams. One special type of overhanging beam is the crane trolley monorail. Lateral buckling of overhanging monorails under idealized loading and boundary conditions has been studied in the past using classical mathematical procedures. This paper aims to present a detailed investigation of overhanging monorails using finite element analysis. Effects of different loading and boundary conditions were studied in detai...
Leakage control by optimal valve operation Özkan, Tülay; Merzi, Nuri; Department of Civil Engineering (2008) The main function of a water distribution system is to supply water in sufficient quantity at appropriate pressure with an acceptable quality and as economically as possible. Water leakage in distribution networks may account from 5% to 50% and even larger of the total water delivered. The amount of leakage in a network is directly related to system service pressure. Therefore, reductions in high service pressures will result in considerable reductions in leakage. A methodology for leakage reduction has bee...
