Experimental and analytical analysis of vaned savonius turbine performance under different operating conditions
(Elsevier, 2019-05-13)
Global energy production is shifting towards more distributed technologies, where power generation takes place close to people. A vaned Savonius wind turbine is one of the possible solutions, which can fulfil the requirements ...
CFD Modelling of a Centrifugal Compressor with Experimental Validation through Radial Diffuser Static Pressure Measurement
(Hindawi, 2019)
This paper compares experimental static pressure measurement with CFD simulation in a centrifugal compressor at 12 points through the diffuser. Three mass flow rates are selected, each for three operating speeds giving ...
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. ...
Flow Control Methods and Their Applicability in Low-Reynolds-Number Centrifugal Compressors—A Review
(MDPI, 2018)
The decrease in the performance of centrifugal compressors operating at low Reynolds numbers (e.g., unmanned aerial vehicles at high altitudes or small turbomachines) can reach 10% due to increased friction. The purposes ...
Loss Development Analysis of a Micro-Scale Centrifugal Compressor
(Elsevier, 2018)
The ever-increasing demand for more efficient energy conversion has placed designers under increasing pressure to develop processing equipment that can meet contemporary needs. It has long been known that a decreasing ...
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 ...
