The aim of this study is to develop an interferometric technique to measure micron level clearances occurring in small piston-cylinder arrangements; such as hermetically sealed compressors. A Cartesian model of the piston cylinder arrangement is manufactured and lateral and vertical motions are generated via a step motor, and micrometers, respectively, to simulate the piston motion and the change of clearance during the motion. Experiments are conducted in air and a lubricant. Measurements show the important effect of surface waviness of the mirror and the effect of the motion of the carriage at micron level measurements.

AN INTERFEROMETRIC TECHNIQUE FOR MEASURING MICRON LEVEL CLEARANCES FILLED WITH A LUBRICANT Yildirim, Murat; Dursunkaya, Zafer; Okutucu Özyurt, Hanife Tuba (2010-10-20) The aim of this study is to develop an interferometric technique to measure micron level clearances occurring in small piston-cylinder arrangements; such as hermetically sealed compressors. A Cartesian model of the piston cylinder arrangement is manufactured and lateral and vertical motions are generated via a step motor, and micrometers, respectively, to simulate the piston motion and the change of clearance during the motion.

Development of a pressure-based solver for both incompressible and compressible flows Denk, Kerem; Sert, Cüneyt; Department of Mechanical Engineering (2007) The aim of this study is to develop a two-dimensional pressure-based Navier-Stokes solver for incompressible/compressible flows. Main variables are Cartesian velocity components, pressure and temperature while density is linked to pressure via equation of state. Modified SIMPLE algorithm is used to achieve pressure-velocity coupling. Finite Volume discretisation is performed on non-orthogonal and boundary-fitted grids. Collocated variable arrangement is preferred because of its advantage on staggered arrang...
DEVELOPMENT OF MICROEXTRACTION TOOLS COMPATIBLE WITH THERMAL AND SOLVENT DESORPTIONS SUITABLE FOR TARGETED AND UNTARGETED ANALYSIS Kahremanoğlu, Kübra; Boyacı, Ezel; Department of Chemistry (2023-1-25) Solid phase microextraction (SPME) is one of the essential tools present in the analytical toolbox integrating the sampling and sample preparation into a single step. Because of this unique feature, SPME is distinct among other technologies as a tool suitable for in-vivo, on-site, and in-vitro applications. Up to date, a plethora of extractive phases suitable for targeted and untargeted studies have been developed for SPME. However, usually, they are only suitable for solvent or thermal desorption followed ...

Development of a Parametric Equation to Predict the Joint Shear Strength Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-05-01) This paper presents an analytical study that focuses on the development ofa parametric equation to predict the joint shear strength. In this analytical study, adatabase containing geometric properties, material strengths, configuration detailsand test results of reinforced concrete beam-to-column connection subassembliestested under cyclic loading is established. Then, based on the experimental results,parameters affecting joint shear capacity are determined. The most influentialparameters are selected and ...
