Experimental flow field investigation in a centrifugal compressor vaned diffuser
Pinarbasi A.; Johnson M.W. (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 ... -
Numerical and experimental study of flow and heat transfer around a tube in cross-flow at low Reynolds number
Buyruk E.; Johnson M.W.; Owen I. (Elsevier Science Inc, New York, NY, United States, 1998)A numerical and experimental study of the laminar flow and heat transfer characteristics of a cylinder in cross-flow is presented. The computational technique used is a stream function-vorticity formulation of the laminar ... -
Off-design flow measurements in a centrifugal compressor vaneless diffuser
Pinarbasi A.; Johnson M.W. (1995)Detailed measurements have been taken of the three-dimensional velocity field within the vaneless diffuser of a backswept low speed centrifugal compressor using hot-wire anemometry. A 16 percent below and an 11 percent ... -
A study of Reynolds stresses and loss generation at the inlet to a centrifugal vaneless diffuser
Pinarbasi A.; Johnson M.W. (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 ... -
Three-dimensional flow measurements in conical and straight wall centrifugal compressor vaneless diffusers
Pinarbasi A.; Johnson M.W. (Professional Engineering Publishing, 1996)In the current work three-dimensional flow measurements in two types of centrifugal compressor vaneless diffuser were obtained using hot wire anemometry. The first diffuser was conical, designed to give a constant flow ...
