The solar evaporative crystallization process at Lake Katwe was studied using brine evaporation rates, thermal, convection, and radiation energy losses as well as reported meteorological data around the salt lake basin. A simulation model of a salt pan was developed on a lumped basis to study its...

In this work, combustion process of diesel and biofuel blends is studied experimentally in an isothermal oven. Blends with respectively 20%, 40% and 60% of Ethanol (E20, E40, E60), 20%, 40% and 60% of Methanol (M20, M40, M60), and 20%, 40%, 60%, 80% and 100% of Biodiesel (B20, B40, B60, B80, B100)...

Wind Energy is one of the important sources of renewable energy. There is a need to prepare the availability of wind energy in the area where there is no measured wind speed data. For this type of situation, it seems to be necessary to predict the wind energy potential using such as wind speed using...

A Computational Fluid Dynamics (CFD) simulation using CFX, ANSYS 11.0 , has been carried out using a multiphase flow model with an Eulerian-Eulerian approach for an airlift column photobioreactors (PBR). Transient simulations were performed for three inlet air flow, 2, 3 and 5 l/min. The contours...

This paper reports the synthesis and the investigation of the properties and performance of Fe-Al catalysts modified with Cu or Co for the steam reforming of ethanol. The materials were prepared by the precipitation method with different Fe/Al ratios. The samples were characterised by the S BET , TG...

This work employs the environmental methodology of Life Cycle Assessment (LCA) in compliance with ISO 14040 and uses software SimaPro® 7.3.2 to compare the environmental impact in process production of flat plate and evacuated tube solar collectors. In addition, an economic analysis was performed...

This study investigates the effect of different pre-treatments on the bio-ethanol production from the soluble compounds of the organic fraction of the municipal solid wastes (OFMSW). The experimental evaluation was performed on leachate samples obtained after mixing OFMSW with water during 10 d. The...

In this work, the stopping power due to free and bound electrons in a plasma target is analyzed for two different kinds of projectile, protons and alpha particles. The stopping of free electrons is calculated using the dielectric formalism, well described in previous literature. In the case of bound...

An unstandarised biodiesel made from Camelina sativa oil, having over a 90 percent by weight of unsaturated fatty acids, were transformed into an epoxidised biodiesel that satisfy the requirements for iodine value, linolenic acid methyl ester content, cetane number, polyunsaturated fatty acids...

Currently there is a big interest to increase the sources of alternative fuels for aviation to get a reduction of their carbon footprint and the deep energetic dependence from fossil fuels of different countries. Although there are studies about how to produce this alternative fuel and if it...

A set of experiments have been carried out in a heavy duty single cylinder engine using high EGR rates and different start of injection angles ( SOI ). Three different fuels (conventional diesel fuel, a diesel-ethanol mixture (e-diesel) and a Fischer-Tropsch fuel (GTL)) have been tested in order to...

The aim of this work is to quantify the life-cycle emissions in terms of CO 2 equivalent grams per megajoule of biodiesel produced from Acrocomia totai, a native oily seed from Paraguay, according to Directive 2009/28/EC. The other key point is to calculate the amount of energy invested to get a...

In an effort to reduce the environmental impact on the landscape caused by the installation of photovoltaic farms, Spanish legislation requires the establishment of a hedge on the perimeter of each plot. The objective of the work described here was to increase our knowledge of the hedge species that...

The structure of the wind turbines nowadays is a critical element due to their importance from the reliability, availability, safety, and cost points of view. This is more relevant when the offshore wind turbine is considered. This paper introduces a novel design of a Fault Detection and Diagnosis...

The present work is about the techno-economic evaluation of a biodiesel industrial unit that exclusively use recycled edible oils as feedstock, for two alternative production technologies. Nowadays, many biodiesel production units use a mixture of virgin vegetable oils and waste cooking oils. The...
