Erosive wear of the parts gas path an axial compressor a turbine is common reason for premature decommissioning equipment. The creation advanced diagnostic system, which will allow determining level blade erosion according to standard parameters without inspection or disassembly, topical Russian transmission enterprises. paper presents preliminary results applying machine learning methods solve...

The structural fracture of the compressor blade is main cause fatigue failure. novelty this paper creative application bent swept-back modeling to turbocharger impeller. This based on a impeller satisfying k-ε turbulence model. A simulation model was established in ANSYS software, fluid–structure interaction calculated three models before and after improvement, results were compared analyzed. o...

Abstract The operating range of a compressor is limited by surge or rotating stall line, among others. Numerical simulations must accurately predict these phenomena. This study based on the experimental CME2, which low-subsonic axial compressor. tip-critical as rotor tip responsible for stall. paper shows that onset flow rate well captured computational fluid dynamics, compared to experiments. ...

A three-dimensional viscous inverse method is extended to allow blading design with full interaction between the prescribed pressure-loading distribution and a specified transpiration scheme. Transpiration on blade surfaces and endwalls is implemented as inflow/outflow boundary conditions, and the basic modifications to the method are outlined. This paper focuses on a discussion concerning an a...

As the main noise source in hydrogen fuel cell system, level of centrifugal air compressor greatly affects comfort vehicle, and can be effectively reduced by optimizing trailing edge sweep angle blade. In this paper, computational fluid dynamics model was used to study influence on aerodynamic performance flow characteristics a for vehicle cells. The Ffowcs Williams–Hawkings equation dynamics–b...

The choice of geometrical shape of the blades has a considerable effect on aerodynamic performance and flow characteristics in axial compressors. In this paper, the effects of the blades shape on the aerodynamic design characteristics are investigated based on Streamline Curvature Method (SCM). Initially, the Streamline Curvature Method (SCM) is used for designing a two-stage axial compressor. ...
