... at different tip clearance of 0.38 τ , 0.77 τ , 1.15 τ , and 1.54 τ and blade tip surface roughness of 0.31 ε and 0.62 ε . The tip clearance of 0.38 τ with blade tip surface roughness of 0.62 ε resulted in the highest stall margin and pressure rise of 20.3% and 4.3%, respectively. The compressor blade loading...

...Yongshun Zeng; Zhifeng Yao; Shijie Zhang; Fujun Wang; Ruofu Xiao Tip clearance in hydraulic machines may complicate the fluid–structure interaction (FSI) effects. In this investigation, a mode-based approach (modal work) is evaluated and employed to quantitatively predict the added mass, added...

... are regarded as low efficiency machines if efficiency is less than 40 percent or 50 percent. Considering that not only low Reynolds number and tip clearance but the design method are the major causes for low performance, we carried out the performance test experimentally using two semi-open centrifugal...
