The primary moisture separator—a key component in the PWR nuclear power plant—determines quality of supplied steam to a turbine. Investigating its characteristics is important because supplying with excessive droplet entrainment results damages pipes, valves, and turbines plant circuits. In this numerical study, particle tracking method Eulerian–Lagrangian methodology used investigate separator...

An innovative axial hydrocyclone separator was designed in which a guide vane installed to replace conventional tangential inlet, potentially aggravating inlet turbulence. The characteristics of velocity distribution, concentration and pressure distribution inside the were obtained through numerical simulation turbulent flow oil water. results showed that field presented good symmetry, eliminat...

An experimental study has been conducted to investigate the flow characteristics over two rounded contour bumps. Vane-type vortex generators or longitudinal aligned passive by-pass jets were implemented in attempt to achieve wake flow control in rounded contour bumps. According to the results collected from the surface oil flow visualisation experiments, it was observed that the use of both the...

In our previous experiments using a wind tunnnel, the flow in a two-dimensional curved diffuser with logarithmic spiral angle was clarified quantitatively about the variation of spiral angle and the existence of a guide vane. The wind tunnel method however requires much time for preparation of the experimental system and for the main experimental procedure . We have recently devised a new exper...

This paper presents a complete dynamic analysis of roller and vane of a rotary compressor widely used for air-conditioners. An approach and a set of equations are developed estimating the type of motion at vane tip and roller interface and calculating the frictional force in accordance with the motion type. The forces on roller caused by relative motion between roller and cylinder wall are anal...

Enterococcus faecalis BM4405-1, a susceptible derivative of the VanE-type vancomycin-resistant E. faecalis strain BM4405, was obtained after growth in the presence of novobiocin, an inhibitor of the GyrB subunit of DNA gyrase. In contrast to findings for BM4405, UDP-MurNAc-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala (pentapeptide[D-Ala]) was the only peptidoglycan precursor found in BM4405-1, and no Va...

An experimental study has been conducted to investigate the effects of vane-type vortex generators in affecting the flow pattern of the wake region using a 1:20 scale tractor-trailer model. The de Haviland wind tunnel of the University of Glasgow was employed in this study. Surface oil flow visualisation, smoke visualisation and twocomponent time-averaged particle image velocimetry measurements...

Worldwide conventional resources of fossil fuel are depleting very fast due to large scale increase in use of transport vehicles every year, therefore consumption rate of oil in transport sector alone has gone very high. In view of this, the major thrust has now been laid upon the search of alternative energy source and also for cost effective energy conversion system. The air converted into co...
