Comparative evaluation of some existing correlations to predict head degradation of centrifugal slurry pumps

Engin, Tahsin; Gür, Mesut (ASME-AMER SOC MECHANICAL ENG, 2003)

In order to optimally design a slurry transportation system, it is necessary to know how the presence of solids will change the performance of the slurry pump to be installed. This paper makes the comparison of some existing ...
Comparison of thermal stresses developed in Al2O3-SG, ZrO2-(12% Si+Al) and ZrO2-SG thermal barrier coating systems with NiAl, NiCrAlY and NiCoCrAlY interlayer materials subjected to thermal loading

Taymaz, İmdat; Mimaroğlu, Abdullah; Avcı, Eşref; Uçar, Vahdet; Gür, Mesut (ELSEVIER SCIENCE SA, 1999)

In this investigation, thermal and structural finite element analysis has been employed to analyse the level of stresses developed in Al2O3-spherical cast iron (SG), ZrO2-(12% Si + Al) and ZrO2-SG coatings subjected to ...
Effects of tip clearance and impeller geometry on the performance of semi-open ceramic centrifugal fan impellers at elevated temperatures

Engin, Tahsin; Gür, Mesut (ELSEVIER SCIENCE INC, 2006)

Centrifugal fans are being widely used in many industrial applications. However, when handling gases with temperatures exceeding 800 degrees C, the use of centrifugal fan impellers are of particular interest since the ...
Exergy analysis of laminar fluid flow in stainless steel microtubes

Parlak, Nezaket; Engin, Tahsin; Küçük, Hasan; Gür, Mesut (INDERSCIENCE ENTERPRISES LTD, 2011)

In the study, exergy analysis of steady laminar fluid flow in stainless steel microtubes with diameters between 103 mu m and 179 mu m were conducted in the adiabatic conditions experimentally. The exergy losses were obtained ...
