In this modern world, the technology is developing day by day and hence, the demand on fossil fuels and power keeps on increasing. Since the demand is very high, it is impossible to power up the entire world using petrol and diesel. The depletion of fossil fuels and the worst impact on environmental pollution have led to the search for renewable clean energies. Micro algae are presently the favourable source of biofuels for the substitution of fossil fuels. This study focused on to extract bio-oil from the Botryococcus algae which has high lipid content, by using pyrolysis method. The Botryococcus algae oil is used as the biofuel in the direct injection (DI) diesel engine. The 90% diesel is blended with 10% Botryococcus algae oil and the test was carried out to analyse the effect of diesel-biofuel on the engine performance, emission and properties such as SFC, BTE, CO, NOx and HC. The experiment was conducted on a single cylinder four stroke diesel engine with diesel and biofuel blend at varying loads. The performance and emission results of the blended biofuel and diesel were compared, and the performance results, shows the biofuel blend is almost closer to the diesel, and the biofuel blend gives less emission than the diesel.

The modern developments in wind turbine fault diagnosis and condition monitoring are urged in recent times. This paper aims to identify different types of faults which occur on wind turbine blade as they are prone to vibration stress due to environmental and weather condition. The fault diagnosis problem was carried out using machine learning approach. This study was carried out using vibration sources which has been acquired from good and other fault condition blades using data acquisition system. From the recorded signals, histogram features were extracted and classified using meta classifiers. From the classifiers, a better data-model is suggested for a multi-class problem in wind turbine blade fault diagnosis.

The main objective of this study is to improve the wind energy productivity by implementing the condition monitoring technique for wind turbine blades through vibration source. The fault detection and the isolation of the fault which affects the wind energy productivity were carried using machine learning algorithms. In this study, a three bladed horizontal axis wind turbine was chosen and the faults like blade bend, blade cracks, hub-blade loose connection, blade erosion and pitch angle twist were considered as these are the faults which affect the turbine blade. Initially, vibration sources were collected from the wind turbine using piezoelectric accelerometer and from that vibration source; needed features are extracted using ARMA through MATLAB. From the extracted feature, the dominating feature is selected using J48 decision tree algorithm and with the selected features, fault classification has been carried out. The fault classifications were carried out using Bayesian, function and lazy classifiers.

In today's world, the applications of diesel engines are gradually increased in the area of agricultural and especially in commercial vehicle sectors. The present scenario emphasises necessarily for the development of better techniques to improve the efficiency of the diesel engine and also the adverse effect of fossil fuels on the environment. The purpose of this work is to investigate the consequence of biodiesel blends with diesel on exhaust gas temperature and emission characteristics. In this work, the exhaust emissions and exhaust gas temperatures were measured in a four stroke, single cylinder, and constant speed diesel engine fuelled with Calophyllum inophyllum methyl ester (CIME) and its blends with diesel. The different blends such as B20, B40, B60 and B80 of CIME blends with diesel and B100 (CIME) and diesel (100%) were used for this test run. The test results of different blends were compared with diesel fuel and presented in this paper.

Desalination by humidification dehumidification processes is a promising simple, cost effective and low maintenance concept. It works on the principle of air humidification at high temperature and dehumidification at relatively low temperatures. The present study is for evaluating the performance of the humidifier with coconut coir as packing material used for air humidification in the solar humidification dehumidification (HDH) desalination plant. Experiments were carried out on the humidifier packing for different flow rates of water and its temperature. Humidifier range, effectiveness and efficiency, evaporation rate of water, heat and mass transfer rates are studied by experimentally for different flow rates of hot water and its temperature. The hot water flow rate is varied from 125 to 225 LPH with an increment of 25 LPH and water temperature from 38 to 54°C. It is found that at water flow rate of 200 LPH and at 0.55 m3/s volume flow rate of air, effectiveness of humidifier found to be maximum of 0.74.

The present investigation is mainly focused on the reduction of NOX emissions from the diesel engine. In this experimental work, the diesel engine has initially run by diesel alone, secondly, 10% cottonseed methyl ester biodiesel (B10) and finally emulsion of 10% water with B10 (WiB10E) in combination. The emulsified biodiesel WiB10E shows the maximum reduction of NOX emissions in comparison with the pure diesel and B10 fuel operations. Also, due to the cooling effect provided by the water in the combustion chamber, the WiB10E shows the slight increase of the HC and CO emissions. Since WiB10E fuel has a boiling point difference, it leads to secondary atomisation. The WiB10E has shown the higher cylinder pressure of 65.92 bars at a crank angle of 366° due to microexplosion. Hence, emulsified biodiesel fuel is efficient in the reduction of NOX emissions amongst all the techniques.

Nowadays, the effects of the incorporation of electric vehicles (EVs) have to be taken into consideration with care, since it may result in unfeasible operations for the grids (especially for the Smart Microgrids). Smart microgrids (SMs) seem to be the best solution for the management of modern low voltage (LV) grids with distributed energy resources (DER). The main purpose of this paper is to investigate the effects of different EVs' charging and discharging strategies in a SM. With EVs and absence of DERs and therefore satisfaction of the full load from the upstream network, is considered as the base case. For each scenario, six different charging technologies are examined. In addition, three different pricing policies based on system marginal price (SMP) are considered. All different cases are compared between them to determine which one is the most advantageous in terms of operational cost.

The enhancement of ZnSe/Si Heterojunction by adding some elements (V, In and Cu) as impurities is the main goal because they contribute to the manufacturing of renewable energy equipment, such as solar cells. This paper describes the preparation of thin films ZnSe with V, In and Cu doped using thermal evaporation method with a vacuum of 10-5 Torr. The thin film was obtained from this work could be applied in heterojunction solar cell because of several advantages including high absorption coefficient value and direct band gap. The samples prepared on a glass and n-type Si wafer substrate. These films have been annealed for 1 h in 450 K. X-ray diffraction XRD results indicated that ZnSe thin film possesses poly-crystalline structure after doping with preferential orientation (111) and the atomic force microscopy (AFM) were used to examine the surface morphology. Optical studies were done using UV-Visible spectroscopy and the band gap energy was found to decrease with doping. Hall measurements showed that all the films are p-type with high carriers concentration (3.26 × 1017 cm-3) in ZnSe:Cu thin film. The built in potential was determined from the C-V measurements which revealed an abrupt junction for all heterojunction samples. The conversion efficiency calculated from dark and illuminated I-V characteristics of ZnSe/Si solar cell pure and doping. The chances for achieve type of doping can be improved by designing growth conditions that destabilise the formation of compensating centres, which is important for optical device applications, the effect of doping on main different factors such as open-circuit voltage, short-circuit current density, fill factor, the photovoltaic conversion efficiency of ZnSe pure and doped. The results reveal high efficiency for ZnSe:Cu heterojunction solar cell.

The polymeric composites material considered as one of the most isolated materials, but they have a good mechanical flexibility. The main idea of modifying these materials to be one of the applicable materials in environmental aspects. Reducing the temperature inside buildings by coating them with the modified materials will give very good results in decreasing the electrical power used. In this study, polymeric composites material were prepared a by hand- layup technique from epoxy resin (EP) as a matrix and Copper (Cu) powder with average diameter (240.91 nm) as fillers with different weight percentage (5%, 15%,25%, 35%, and 45%) to resin. Glass transition temperature and Hardness testing were investigated. The results show the maximum Glass transition temperature (Tg) of (EP/Cu) composites were the value (58.949°C) at (65%EP + 35%Cu). Increase hardness with Copper concentration increase, and it has maximum values of (83.9) for (55%EP + 45%Cu). This composite can be used in the coating surfaces and floors to match the temperature of our country warm in summer.

In the current study, we want to optimise the removal efficiency of methyl orange using decorated multi-walled carbon nanotubes (MWCNTs) with different amount of ZnO nanoparticles. For this purpose, we investigate the influence of several parameters such as UV irradiation time, pH of the solution and weight fraction of photocatalysts on the removal efficiency using 2-level factorial design. The statistical analysis results using Half-normal plot demonstrate that all of the main factors have a significant effect on the removal efficiency of pollutant. Meanwhile, the results of t test and Pareto charts reveal that UV irradiation time and weight fraction have a positive effect on the responses. However, the influence of pH on the removal efficiency of methyl orange is negative. The results of the optimisation process show that for maximising the removal efficiency of pollutant, the optimal level of irradiation time, pH and weight fraction should set to 25 min, 4 and 0.5 %wt, respectively.
