Oil feed grooves are implemented in reciprocating compressor piston applications to assure a constant supply of lubricating oil on bearing surfaces and decrease friction loss. In a hermetically sealed compressor, due to small clearances encountered, oil supply becomes critical in order not to operate in boundary lubrication regime. Due to the small size of the piston and small piston cylinder clearance, a partial lubrication regime is present. In the current study, a model that solves Reynolds’ equation for piston-cylinder lubrication and the average Reynolds’ equation that considers the effect of roughness on partially lubricated bearing for a compressor piston with oil feed grooves is developed. A parametric study is carried out to investigate the effects of piston design parameters and then arrive at an improved piston performance by using alternative designs for oil feed groove and the other design parameters.

Effect of Oil Feed Groove on Compressor Piston Lubrication
Hacıoğlu, Bilgin; Dursunkaya, Zafer (2008-07-14)
Oil feed grooves are implemented in reciprocating compressor piston applications to assure a constant supply of lubricating oil on bearing surfaces and decrease friction loss. In a hermetically sealed compressor, due to small clearances encountered, oil supply becomes critical in order to prevent the boundary lubrication.

Development and comparative evaluation of a new structural modification method in application to aircraft structures
Köksal, Sertaç; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2006)
In the development of engineering products, it is necessary to predict dynamic properties of the modified structures. Achieving such predictions by using the structural properties of the original structure and information on the modifications is commonly referred to as structural modification analysis. In this thesis, Özgüven’s Structural Modification Method and Sherman-Morrison Method are selected as exact methods for structural modifications to predict the dynamics of a locally modified structure. Also, a...
Dynamic modeling of spindle-tool assemblies in machining centers
Ertürk, Alper; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2006)
Regenerative chatter is a well-known machining problem that results in unstable cutting process, poor surface quality, reduced material removal rate and damage on the machine tool itself. Stability lobe diagrams supply stable depth of cut ا spindle speed combinations and they can be used to avoid chatter. The main requirement for generating the stability lobe diagrams is the system dynamics information at the tool tip in the form of point frequency response function (FRF). In this work, an analytical model ...
Investigating the formation of intermetallic compounds during friction stir welding of magnesium alloy to aluminum alloy in air and under liquid nitrogen
Mofid, M. A.; Abdollah-zadeh, A.; Gür, Cemil Hakan (Springer Science and Business Media LLC, 2014-03-01)
This research demonstrates the use of submerged friction stir welding under liquid nitrogen as an alternative and improved method for creating fine-grained welds, and hence, to alleviate formation of intermetallic phases. Magnesium alloy and aluminum alloy were joined by friction stir welding in two environments, namely air and liquid nitrogen, with 400 rpm rotation and 50 mm/min travel speed. The temperature profile, microstructure, scanning electron microscope energy dispersive X-ray spectroscopy analysis...
Investigation of Moisture Dissipation in Foam-Based Warm Mix Asphalt Using Synchrotron-Based X-Ray Microtomography
Kutay, M. Emin; Öztürk, Hande Işık (American Society of Civil Engineers (ASCE), 2012-06-04)
Foam-based Warm Mix Asphalt (WMA) technologies decrease the viscosity of the asphalt so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and temperature drops. During the process of dissipation of foam, depending on the environmental conditions, the moisture may not escape and may be trapped inside the mixture. This trapped moisture can cause detrimental failures by breaking the adhesive bonds between the aggregates and the asphalt bind...
