LDV Measurements in the Endwall Region of an Annular Turbine Cascade Through an Aerodynamic Window
Laser-Doppler velocimetry measurements through a one millimeter hole in the casing of an annular turbine cascade were performed in the endwall region downstream of the blade row. Complementary threehole pressure probe measurements were also taken downstream of the nozzle blades, as well as blade surface pressure measurements. The object of this study was to devise methods for the measurement cl...
متن کاملEffect of Slot at Blade Root on Compressor Cascade Performance under Different Aerodynamic Parameters
The effects of compressor aerodynamic parameters, such as pitch-chord ratio, aspect ratio, and fillet, on the cascade performance have been studied in this paper. Slot configuration at the root of the blade has been proved to be an efficient passive control method for the corner separation control in compressor cascade. The combined effects of the pitch-chord ratio, aspect ratio, and blade fill...
متن کاملEffect of Camber and Thickness on the Aerodynamic Properties of an Airfoil in Ground Proximity (RESEARCH NOTE)
A linear vortex panel method is extended to include the effect Abstract of ground proximity on the aerodynamic properties of two dimensional airfoils. The image method is used to model the ground effect . According to the results, lift coefficient of an airfoil may increase or decrease in ground effect based on a combinative effect of its camber, thickness, angle of attack and ground clearance....
متن کاملAn Aerodynamic Investigation of a Centrifugal Compressor for HCFC123
The experimental investigation of a centrifugal compresso r is carried out to improve HCFC123 compression performance. A CFCll c ompressor applying HCFC123 shows a lowered adiabatic head rise, efficie ncy, and volume flow. Another CFC!l compressor with HCFC123 and a modifie d impeller shows a result comparable to the CFCll compression case. A tan dem impeller is designed to cover the volume flo...
