Computation of flow in a target flowmeter
Temel, Uemit N.; Oeztuerk, Adnan; Pinarbasi, Ali (NATL INST SCIENCE COMMUNICATION, 2008)Present study determines optimum geometry for target fluidic flowmeter capable to function at small Reynolds numbers (<300). Using fluent code solver, numerical studies were carried out for gasoil measurements at various ... -
Effect of impeller-diffuser radial gap ratio in a centrifugal pump
Ozturk, Adnan; Aydin, Kadir; Sahin, Besir; Pinarbasi, Ali (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2009)In this study, effects of flow behavior in a non-traditional centrifugal pump, whose diffuser was subjected to different radial gaps, were investigated numerically using multi-purpose FLUENT code. Flow was assumed to be ... -
Experimental hot-wire measurements in a centrifugal compressor with vaned diffuser
Pinarbasi, Ali (ELSEVIER SCIENCE INC, 2008)The purpose of this study was to improve the understanding of the flow physics in a centrifugal compressor with vaned diffuser. For this reason three component hot wire measurements in the vaneless space and vane region ... -
Flow analysis in centrifugal compressor vaneless diffusers
Tatar, Ozturk; Ozturk, Adnan; Pinarbasi, Ali (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2008)Flow computations have been performed in vaneless diffuser (diam, 1 m), in low speed backswept centrifugal compressor using finite volume method (FVM),coupled with Standard k-epsilon turbulent model by solving oil commercial ... -
Turbulence measurements in the inlet plane of a centrifugal compressor vaneless diffuser
Pinarbasi, Ali (ELSEVIER SCIENCE INC, 2009)Detailed flow measurements at the inlet of a centrifugal compressor vaneless diffuser are presented. The mean 3-d velocities and six Reynolds stress components tensor are used to determine the turbulence production terms ... -
Wedge type vaned diffuser flow measurements in a low speed centrifugal compressor
Temel, Umit Nazll; Ozturk, Adrian; Pinarbasi, Ali (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2008)This study establishes effectiveness of vaned diffuser in comparison with vaneless diffusers in centrifugal compressor. Hot wire measurements at three inter-vane positions for mean velocity, turbulent kinetic energy and ...
