Off design Reynolds stress tensor measurements in a centrifugal compressor vaneless diffuser
(ASME, New York, NY, United States, 1994)Detailed off-design (16% below and 11% above design) flow measurements have been taken within a backswept centrifugal impeller vaneless diffuser using hot wire anemometry. 3-d velocity and six Reynolds stress components ... -
A study of Reynolds stresses and loss generation at the inlet to a centrifugal vaneless diffuser
(American Society of Mechanical Engineers (ASME), 1995)Detailed flow measurements at the inlet to a centrifugal compressor vaneless diffuser are presented. The mean velocities and six component stress tensor are used to determine the turbulence production terms which lead to ... -
Experimental flow field investigation in a centrifugal compressor vaned diffuser
(American Society of Mechanical Engineers (ASME), 1995)The purpose of this study was to improve the understanding of the flow physics in a centrifugal compressor vaned diffuser. A low speed compressor with a 19 bladed backswept impeller and diffuser with 16 wedge vanes was ... -

Wavelength converter/amplifier with fine tunability
(IEEE, Piscataway, NJ, United States, 1998)The results of the study of a novel monolithic wavelength converter/amplifier which can be tuned, with the application of an external field are presented. The tuning range is Dl=300 angstrom about the operation wavelength, ... -
Formation of boroncarbur-ceramic powder mixture and its characteristics [Borkarbürün seramik tozu ile şekillendirilmesi ve karakterizasyonu]
(2002)In order to extend the life span of the elements of machines, the methods, which will reduce wearing and deformation, are investigated. Hence the need for composite materials production techniques has arisen. The objective ... -
Determination of boundaries, geological outcrops and structural features of the Sivas Tertiary Basin/Turkey using Landsat TM/ETM+ and SPOT XS images
(International Society for Photogrammetry and Remote Sensing, 2004)The Sivas Basin is one of the most well known major Tertiary basins of the Anatolia connected with the evolution of the Neotethyan Ocean. Central Anatolian Thrust Belt contains realms of this ocean and bounds the basin ... -
Grinding of ceramic raw materials by a standard Bond mill: Quartz, kaolin and K-feldspar
(2005)The kinetics of batch dry grinding of ceramic raw materials, which are quartz, kaolin and K-feldspar, from the feeds of sieve sizes -3-350+2-360, -2-360+1.400, -1.400+0.850, -0.850+0.600, -0.500+0.425 and -0.300+0.212 mm ... -
Landslide susceptibility mapping methods and use of artificial neural networks
(2005)Landslides have a large quantity of the natural disasters world-wide, this trend will increase in the future due to increased urbanization and development. The creation of maps of susceptibility, danger and risk is very ... -
Economic analysis of ports by artificial intelligence
(Middle East Technical University, 2005)The economical analysis model for coastal projects consists of two interrelated sub-models: 1) Artificial Intelligence to determine the rates and capacity of cargo by considering the economical development of hinterland ... -
Indication of geohazard risk and economic value of gypsum deposits in the Tertiary Sivas Basin (Turkey) using ASTER and landsat ETM+ images
(2005)The Tertiary Sivas Basin contains widespread, tectonically deformed deposits of massive Oligocene gypsum. This unit is one of the most important factors controlling the tectono-stratigraphic evolution of the basin insofar ... -
Large eddy simulation of spanwise rotating turbulent channel and duct flows by a finite volume code at low reynolds numbers
(2005)The objective of this study is to show the highly complex features of rotational turbulent flow using a widely known finite volume code. The flow subjected to an orthogonal rotation is investigated both qualitatively and ... -
