Although, more than two-thirds of the Earth is covered by water, shortage of potable water is a serious issue that many countries suffer from. Furthermore, the worldwide rapid growth of industry and population has resulted in a large boom in demand for fresh water. The solar still, in many respects, is an ideal source of fresh water for both drinking and agriculture; it is one of the most important and technically viable applications of solar energy. There are many types of solar still; the simplest and most proven is the basin type. Investigations showed that the basin-type solar still has been found to be of limited performance. Numerous experimental and numerical investigations on basic types of solar still have been reported in various literatures. An extensive review for solar desalination systems has been carried out in this paper. © 2010 Elsevier Ltd. All rights reserved. Source

Solar still is one of the best solutions to solve water problem in remote arid areas. This device is not popular because of its lower productivity. One of the methods to increase the productivity is by decrease the volumetric heat capacity of the basin. A layer of water with wick material in the basin will increase the evaporation area and enhance the production. A basin type double slope solar still with mild steel plate was fabricated and tested with minimum mass of water and different wick materials like light cotton cloth, sponge sheet, coir mate and waste cotton pieces in the basin. Still with aluminium rectangular fin arranged in different configurations and covered with different wicks were also tested. It was found that, the still with light black cotton cloth is the effective wick material. The still with rectangular Aluminium fin covered with cotton cloth and arranged in length wise direction was more effective. The still was theoretically modeled. The variation in transmittance of the cover was considered in the proposed model. The total radiation on the covers was taken as input. Theoretical values of water and glass temperatures using proposed model were compared with theoretical values obtained by Dunkle model and actual experimental values. It was found that the theoretical production rate using the proposed model were close to the experimental. © 2010 Elsevier Ltd. Source

This paper presents the control for three-phase multilevel cascaded H-bridge inverter for photovoltaic (PV) system. The maximum power point tracking (MPPT) is capable of extracting maximum power from the PV array connected to each DC link voltage level. The MPPT algorithm is solved by perturbation and observation method (P&O). Space vector pulse width modulation (SVPWM) algorithm uses a simple mapping to generate gate signals for the inverter. The location of the reference vector and time are easily determined. The adjustments of modulation index and phase angles are synthesized onto field programmable gate array (FPGA) by means of hardware description language (VHDL). A digital design of the generator SVPWM using VHDL is proposed and implemented on FPGA. This is done to achieve high dynamic performance with low total harmonic distortion (THD). Simulation and experimental results are given to verify the implemented SVPWM control for PV system in terms of THD. © 2012 Elsevier Ltd. Source

In this paper, a new approach in Bacterial Foraging Optimization algorithm is proposed to reduce the total power loss and to improve the voltage profile of the radial distribution systems, in the presence of Distributed Generation unit. The proposed method aims to modify the performance of the Bacterial Foraging Optimization algorithm. The test results obtained from Modified Bacterial Foraging Optimization algorithm are also compared and found to be better and in close agreement with the Bacterial Foraging Optimization algorithm. The achievability and convenience of the optimization methods proposed have been demonstrated on 12-bus, 34-bus, and 69-bus radial distribution system consisting of 11, 33, and 68 sections, respectively. MATLAB, Version 7.10 software is used for simulation. © 2013 Elsevier Ltd. All rights reserved. Source

The melting of paraffin wax dispersed with Al 2O 3 that is heated from one side of a square enclosure with dimensions of 25mm×25mm is investigated numerically. The stream function, isotherms and liquid-solid interface at different stages of the melting process are presented and discussed. The effect of orientation of the heating surfaces of a square cavity and the volumetric concentration of Al 2O 3 in paraffin wax on the melting performance of the latent heat storage system is analysed. © 2011 Elsevier Ltd.
