Experimental and numerical investigation of inter-ring gas pressures and blowby in a diesel engine Dursunkaya, Zafer; Richardson, Dana E. (1993-01-01) Inter-ring gas pressures and blowby in a diesel engine were investigated analytically and compared to experimental data measured at three engine speeds. Coupled simulations of ring dynamics, ring lubrication and inter-ring gas dynamics were carried out using the RINGPAK software, a code for the integrated analysis of ring pack performance and tribology. Inter-ring pressures and ring dynamics are known to have an important effect on the "blowback" mechanism of in-cylinder oil consumption, i.e. that of oil-la...
Experimental and numerical investigation of flow under radial gates Tanyeri, Mahmut; Köken, Mete; Aydın, İsmail; Department of Civil Engineering (2021-8-10) Radial gates are commonly used in spillways. At partial gate openings empirical equations, which were obtained from experimental work conducted in 60’s, are used to calculate the discharge passing through. However, there are some discrepancies between the discharge values obtained from these equations and the ones from numerical calculations based on finite volume method and hydraulic models. It is aimed to put forward the source of these differences. For this purpose, experiments and numerical calculations...
Experimental and numerical modeling of heavy-oil recovery by electrical heating Hascakir, B.; Babadagli, T.; Akın, Serhat (Society of Petroleum Engineers; 2008-12-01) Electrical heating for heavy-oil recovery is not a new idea but commercialization and wider application of this technique require detailed analyses for determination of optimal application conditions. In this study, applicability of electrical heating for heavy-oil recovery from two heavy-oil fields in Turkey (Bati Raman and Camurlu) was tested experimentally and numerically. The physical and chemical properties of the oil samples for the two fields were compiled and measured. Then, core samples were expose...
Experimental and numerical investigation of a pressure swirl atomizer Sumer, B.; Erkan, N.; Uzol, Oğuz; Tuncer, İsmail Hakkı (2012-01-01) © ICLASS 2012 - 12th Inte. Con. on Liquid Atom. and Spray Systems. All rights reserved.The flow structure inside a pressure swirl atomizer is investigated using high-speed shadowgraphy techniques and computational fluid dynamics tools. The hollow cone spray properties are detected using Phase Doppler Particle Analyzer. The experimental and numerical results are analyzed and compared. The aircore inside the pressure swirl atomizer is visualized at high temporal and spatial resolutions with the high-speed sha...
Experimental and numerical investigation of a jet vane of thrust vector control system Söğütcü, Burak.; Perçin, Mustafa; Department of Aerospace Engineering (2019) Thrust vectoring is generally used in tactical missile systems when attitude control with conventional control systems is inadequate. One of the most widely used thrust vectoring method is to employ jet vanes in the divergent section of the rocket motor nozzle to have the desired thrust vectoring. In the present study, the flow over the jet vane of a thrust vector control system is investigated using both numerical and experimental techniques. Three dimensional, unsteady and viscous flow over the jet vane i...
