T. IIZUKA and K. IKEDA Tochigi Works Hitachi, Ltd. Shimotsuga-gun, Tochigi-ken, Japan, 329-44 Since applications of rotary compressors driven by inverter motors have become more widespread, l~bricating problems with the sliding parts have been appearing. The sliding parts require sufficient antiseizure and wear-resistant properties under the boundary lubricating conditions. The authors have dev...

Investment cast aerospace components are prone to defects related to solidification process. The hollow columnar-grained aero engine Vane casting, being discussed in this paper, suffers further from extraneous defects such as inclusions, core shift and resultant dimensional deviations. Due to its design complexity and stringent specifications, non-destructive evaluation (NDE) of this component ...

In Sliding Vane Rotary Compressors, as well as in most of positive displacement machines, the oil is injected to accomplish sealing and lubrication purposes. However, the oil injection could produce an additional outcome during the compression phase with a great saving potential from the energetic point of view. Being the air inside the cell at a higher temperature than the oil injected, a cool...

Regulation structures such as submerged vane are needed to reduce and eliminate environmental damage due increased flooding in rivers. In particular, scours on the outer bank flow velocities cause river bed change deteriorate. this study, effect was investigated experimentally by using 3-array areas close bank. The experimental results were performed open channel setup. Computational Fluid Dyna...

The mixing of oil and gas forms the foundation deep-sea extraction transportation. However, traditional conveying equipment has low efficiency high failure rates. In this study, a spiral axial flow liquid multiphase pump was used as base model. Eulerian model RNG turbulence were for numerical simulations to analyze internal field pump. A modification scheme proposed twist airfoil shape create t...

Due to machining techniques and dust deposition, gas turbine upstream slots vane roots are always filleted, significantly affecting the cooling performance of endwall. The effects slot fillet root on endwall were investigated by solving three-dimensional Reynolds-averaged Navier–Stokes (RANS) equations with shear stress transport (SST) k–ω turbulence model. results indicate that velocity distri...
