Centrifugal compressor tip clearance and impeller flow
(Springer Verlag, 2016)
Compressors consume a considerable portion of the electricity used in the industrial sector. Hence, improvements in compressor efficiencylead to energy savings and reduce environmental impacts. The efficiency of an unshrouded ...
Experimental study of centrifugal compressor vaneless diffuser width
(Korean Society of Mechanical Engineers, 2013)
Seven different vaneless diffuser designs for a centrifugal compressor, varying only in diffuser width, were studied experimentally. The studied diffuser widths versus impeller exit width were 1.0, 0.903, 0.854, and 0.806. ...
Influence of the axial turbine design parameters on the stator–rotor axial clearance losses
(Sage Journals, 2014)
The drive towards lower emissions in aerospace engines promotes more efficient and physically smaller engines. One way to decrease the size of the axial turbine is to minimize the distance between successive stator and ...
Experimental study of centrifugal compressor tip clearance and vaneless diffuser flow fields
(Sage Journals, 2013)
Three vaneless diffuser designs, varying in diffuser width, for centrifugal compressor were studied experimentally. Along with the diffuser width, the tip clearance was altered. The compressor overall performance and ...
Investigation of the Stage Performance and Flow Fields in a Centrifugal Compressor with a Vaneless Diffuser
(Hindawi, 2014)
The effect of the width of the vaneless diffuser on the stage performance and flow fields of a centrifugal compressor is studied numerically and experimentally. The diffuser width is varied by reducing the diffuser flow ...
Importance of the vane exit mach number on the axial clearance-related losses
(Sage Journals, 2016)
More efficient and physically smaller axial turbine designs are promoted to lower emissions and increase revenue. The physical size and the weight of the axial turbine can be minimised by adjusting the distance between ...
Numerical analysis of working fluids for large scale centrifugal compressor driven cascade heat pumps upgrading waste heat
(Elsevier, 2020-05-14)
Heat pump technology has the capability to upgrade unusable low-temperature waste heat and make the upgraded heat usable for different types of industrial and domestic heating applications. Heat upgrading could allow to ...
