“…Papalia et al. 28 utilized the PIV technology to investigate rotor-IGVs unsteady aerodynamics interaction in a 1.5 stage axial flow compressor under off-design conditions. The results indicated that the excitation force to IGVs reached maximum when the IGVs outlet angle aligned with detached rotor shocks.…”

To achieve the energy conservation and sustainable development, the prewhirl regulation by inlet guide vanes is proposed and rapidly developed for the compressor and pump. The inlet guide vanes change the flow pattern at the impeller inlet especially the velocity circulation, and then influence the performance of compressor and pump. This paper presents and discusses researches on the prewhirl regulation by inlet guide vanes. Researches include mechanism analysis of prewhirl regulation, experimental and numerical studies on the flow field, performance of compressor and pump with inlet guide vanes, influence of geometric parameters on performance of inlet guide vanes, and failure mode analysis and corresponding flow control methods.

“…Some authors 23–28 have reported that the unsteady interaction of IGVs was closely related to its wake transport within the passage of IGVs and impeller, as well as the vaneless space between them. The forcing functions of IGVs were studied to explain its influence on rotor blade row.…”

“…Efficiency figure shows that the GV opening values more than 50%, lead to the decrease of efficiency for partial and full engine load. This is due to the high mass flow rate level imposed on the compressor wheel which operates under off-design conditions, Papalia et al [6]. Japikse [7] has studied the decisive factors in advanced compressor design and development.…”
