A sectoral diagnosis method for open switch faults of inverter-fed permanent magnet synchronous motor (PMSM) drives have been described. The proposed defines separate residuals each the six switches as a average difference between reference and measured pole voltage instead direct use instantaneous difference, which has varying AC quantity within one cycle rotation. How to determine plausible thresholds is described effectiveness limitation are analysed. Several sets experimental results...
The prototype generation IV sodium-cooled fast reactor (PGSFR) has been developed by the Korea Atomic Energy Research Institute. This uses sodium as a coolant to transfer core heat energy turbine. Sodium chemical characteristics that allow it violently react with materials such water or steam. When sodium–water reaction (SWR) occurs due leakage breakage of steam generator tubes, high-pressure waves and corrosive products are produced, which threaten structural integrity components...
Korea imports about 97% of its energy resources due to a lack available resources. In this status, the role nuclear power in electricity generation is expected become more important future years. particular, fast reactor system one most promising types for generation, because it can utilize efficiently uranium and reduce radioactive waste. Acknowledging importance policy, long-term advanced SFR development plan was authorized by KAEC 2008 updated 2011 which will be carried out toward...
Korea Atomic Energy Research Institute has been developing a pool-type sodium-cooled fast reactor of the Prototype Gen-IV Sodium-cooled Fast Reactor (PGSFR). To assess effectiveness inherent safety features PGSFR, system transients during design basis accidents and extended conditions are analyzed with MARS-LMR subchannel blockage events MATRA-LMR-FB. In addition, in-vessel source term is calculated based on super-safe, small, simple methodology. The results show that PGSFR meets acceptance...
In this study, the existing knowledge on wetting criterion, that is, intrinsic contact angle, for distinguishing between hydrophilic and hydrophobic textured surfaces is verified experimentally. A precise apparent angle measured micro-, nano-, micro-/nanotextured to quantitatively define surface-wetting conditions. particular, X-ray tomography introduced measure geometric morphologies of nano- surfaces, state clearly visualized using synchrotron imaging. By comparing previous theoretical...
This paper presents a numerical algorithm of the implicit coupling for multi-scale thermal hydraulic analysis developed with specific application integration component scale three-dimensional code, CUPID, and one-dimensional system SPACE. The scheme involves formulating single pressure matrix CUPID SPACE coupled domain, which is then divided into two submatrices to solve each computing domain separately. was verified using theoretical problems vertical pipes an elliptical manometer tube....
In this Article, we describe the generation of pressure gradients on-chip for driving liquid phase separations in submicrometer deep channels. The reported pressure-generation capability was realized by applying an electrical voltage across interface two glass channel segments with different depths. A mismatch electroosmotic flow rate at junction led to pressure-driven our device, a fraction which then directed analysis carry out desired separation. Experiments showed strategy be...
Hydrophobicity is an important parameter in a microscale two-phase thermal hydraulic system because the interfacial force has influential role this system. Previous research been limited to flow regime, with most results indicating that surface hydrophobicity parameter. However, effect on boiling not studied, especially at microscale. This due coupled difficulties of fabrication microchannel and modification its surface. study develops methods for single glass formation hydrophobic The...
