The objective of the present work is to assess the impact of improvements in standard characterization figures of merit of electrical steels, typically found in manufacturers catalogs (B_(50) and W_(10/400)), in the performance of high speed electrical motors. From the motor manufacturer standpoint, changing to new materials may represent a complicated and costly procedure. Besides, the motor manufacturer has to deal with process variability and building tolerances that may overcome minor improvements in the electric steel. The electrical steel manufacturer has to deal with numerous process variables and long and expensive development times to come up with new products. Hence, even a small improvement in the B_(50) and W_(10/400) figures are considered to be great achievements. In order to verify if such improvements really translate into real gains in electrical motors, a series of prototypes were constructed with newly developed electrical steels. The core losses of these prototypes were determined by the loss segregation method. Test results support the conclusion that the standard steel characterization figures of merit do not carry enough information for steel and motor manufacturers to conclude on the performance of an electrical steel grade. A datasheet of the electrical steel is proposed. Such datasheet carries useful information for the electrical motor designer and should also be used in the steel development process as a new product assessment tool.

This paper proposes a modeling and controller design approach for a wind-diesel hybrid system including dump load. The proposed control scheme for power quality is fuzzy PI controller which has advantages of PI and fuzzy controller. Simulation results show that the proposed controller is more effective against disturbances caused by wind speed and load variation than the PI controller, and thus it contributes to a better quality wind-diesel hybrid power system. © (2013) Trans Tech Publications, Switzerland.

A nano-modified superhydrophobic membrane

A nano-modified superhydrophobic membrane

作者： Ávila, Antonio Ferreira De Oliveira, Aline Marques De Barros Silveira Lacerda, Glenda Ribeiro Munhoz, Viviane Cristina Santos, Mayara Cele Gonçalves Santos, Patricia Figueiredo Triplett, Matt Graduate Studies Program in Mechanical Engineering Deparment of Mechanical Engineering Universidade Federal de Minas Gerais - UFMG Av.

This paper focuses on the synthesis of super-hydrophobic membranes. The polymer used in this research is polystyrene (PS), which has low surface energy but not low enough to be characterized as a superhydrophobic material. As hydrophobicity is based on low energy surface and surface roughness, the electrospinning technique was selected as the manufacturing technique. N, N' dimethylformamide (DMF) was employed as the PS solvent. Two groups of PS/DMF solutions were investigated i.e. 20/80 and 35/65. To increase even more the hydrophobicity, nanoparticles of silica, graphene, cadmium, and zinc were dispersed into the PS/DMF solutions. In contrast to results previous published in literature, the PS/DMF weight ratio of 20/80 led to water contact angles (WCA) of 148°, which is higher than the contact angle for the 35/65 ratio, i.e. 143°. This fact seems to be due to the presence of non-evaporated solvent into the PS surface as the 35/65 solution was more viscous. The WCA for membranes with 0.5 wt. (%) of graphene reached 152°, 149°-153° for membranes with nanosilica addition, 151o with 5.0 wt. (%) CdS, and 153°, 163° and 168° with the addition of 5 wt. (%), 10 wt. (%) and 15 wt. (%) of ZnS, respectively. © 2013.

This study investigates the optimization of a ZnO-coated TiO working electrode and the effect of this hybrid electrode on the power conversion efficiency of a dye-sensitized solar cell（DSSC）.This electrode was fabricated by dipping the TiO electrode with the TiCl treatment in a solution of zinc acetate dehydrate[Zn（CH3COO）2?2H2O]and *** effect of the concentration of Zn（CHCOO）?2HO on the band gap of a working electrode and on the power conversion efficiency of a DSSC was also *** the concentration of ZnO decreased to 0.002from 0.004 mol/L,the band gap of the working electrode decreased to 3.08 e V from 3.87 e V,and the power conversion efficiency（η）of the DSSC increased to 3.8573%from 3.3514%.Interestingly,theηof DSSC with a ZnO-coated Ti O2 hybrid electrode substantially exceeded that of the conventional DSSC due to TiO orbital hybridization and an energy barrier between ZnO and TiO that suppressed the electron recombination.

Effects of Taiwan Roselle anthocyanin treatment and single-walled carbon nanotube addition on the performance of dye-sensitized solar cells

Journal of Physics: Conference Series 2014年第1期495卷

作者： C S Chou P J Tsai P Wu G G Shu Y H Huang Y S Chen Department of Mechanical Engineering National Pingtung University of Science and Technology Pingtung 912 Taiwan Department of Food Science National Pingtung University of Science and Technology Pingtung 912 Taiwan Engineering Product Development Singapore University of Technology and Design 20 Dover Drive 138682 Singapore Nuclear Materials Joint Lab Tsinghua University Graduate School Tsinghua University City Park (518055) Shenzhen China

This study investigates the relationship between the performance of a dye-sensitized solar cell (DSSC) sensitized by a natural sensitizer of Taiwan Roselle anthocyanin (TRA) and fabrication process conditions of the DSSC. A set of systematic experiments has been carried out at various soaking temperatures, soaking periods, sensitizer concentrations, pH values, and additions of single-walled carbon nanotube (SWCNT). An absorption peak (520 nm) is found for TRA, and it is close to that of the N719 dye (518 nm). At a fixed concentration of TRA and a fixed soaking period, a lower pH of the extract or a lower soaking temperature is found favorable to the formation of pigment cations, which leads to an enhanced power conversion efficiency (η) of DSSC. For instance, by applying 17.53 mg/100ml TRA at 30 for 10 h, as the pH of the extract decreases to 2.00 from 2.33 (the original pH of TRA), the η of DSSC with TiO2+SWCNT electrode increases to 0.67% from 0.11% of a traditional DSSC with TiO2 electrode. This performance improvement can be explained by the combined effect of the pH of sensitizer and the additions of SWCNT, a first investigation in DSSC using the natural sensitizer with SWCNT.

A general transient mathematical model for managing microalgae derived hydrogen production, with temperature dependence of the cultivation medium is developed. For that, the simplified physical model combines principles of classical thermodynamics, mass, species and heat transfer, resulting in a system of differential equations which are discretized in space using a three-dimensional cell-centered finite volume scheme. A Michaelis-Menten type expression is proposed for modeling the rate of H_2 production with dependence on O_2 inhibition. Tridimensional simulations are performed in order to determine the mass fractions distributions inside a compact photobioreactor (PBR), under different operating conditions. A relatively coarse mesh was used (6048 volume elements) to obtain converged results for a large compact PBR computational domain (5m×2m×8m). The largest computational time required for obtaining results was 560 s, i.e., less than 10 min. The numerical results for microalgal growth are validated by direct comparison to experimental measurements. Hydrogen production simulations are conducted to demonstrate PBR intermittent operation (aerobic and anaerobic stages) feasibility and adequate species evolution trends in an indirect biophotolysis approach. Therefore, after experimental validation for a particular H_2 production system, it is reasonable to state that the model could be used as an efficient tool for PBR systems thermal design, control and optimization for maximum H_2 production.
