Abstract This paper presents experimental and numerical CFD studies of the aerodynamics a turbine rear structure (TRS). The TRS test geometry is an engine-realistic state-of-the-art design with polygonal outer case, recessed engine mount bumps, three different vane types: regular vanes, bump vanes in sectors, thick vanes. Using sector types simultaneously was found to be crucial for inlet bound...

R & D Laboratories, DAIKIN INDUSTRIES,LTD. Sakai,Osaka,Japan This paper refers to an improvement of the lubrication in a rolling piston type rotary compressor. The lubrication conditions of lubricated surfaces are examined in running compressor and some parameters of them are numerically analyzed. It is elucidated from the investigation that,when unfavorable condition occurs,the metallic contac...

Numerical analysis for mixed lubrication has been performed in order to investigate the characteristics of sliding surface vane a rotary compressor. The modified Reynolds equation and elastic contact equation, considering roughness, are solved as coupled problem. Using this analysis, investigated by parameter survey on design parameters such vane-slot length clearance between vaneslot. It is fo...

It has been suggested that renin can generate angiotensin I1 at a local vascular level (Thurston & Swales, 1974). For this to occur, angiotensin converting enzyme must also be present. This enzyme occurs predominantly in the vascular bed of the lungs of animals (Vane, 1974), but it has also been shown to occur in the arterial bed of the hind limb of the dog (Aiken & Vane, 1972) and sheep (Osbor...

Male common snipe (Capella gallinago gallinago) produce a 'drumming' sound with their outer tail feathers during their mating dives, but little is known about how this is achieved. We investigated the movements and sound producing capabilities of the outer tail feathers. Using a wind tunnel, we compared observations of the frequencies of sound produced with the predictions from aerodynamic theo...

We have developed a new CO2 heat pump water heater compressor with a single rotary mechanism in practical use for the first time in the world. CO2 refrigerant doesn't destroy the ozone layer, and the global warming potential (GWP) is less than 1/1000 in comparison to hydro-fluorocarbon refrigerants. However the operating pressure of CO2 refrigerant is approximately three times as high as that o...

A brain-computer interface (BCI) is a device that enables direct communication between humans and computers by analyzing neural signals and transforming them into digital signals. A new braincomputer interface system based on the gaze on rotating vane-dependent EEG signal is presented. Classification of EEG signals is done in three sessions: 1-when vane rotates fast and slow in an anticlockwise...
