Experimental investigations on spray flames and emissions analysis of diesel and diesel/biodiesel blends for combustion in oxy‐fuel burner

AbstractPresent research work shows the emissions and flame analysis of oxy‐fuel combustion of diesel and diesel/biodiesel blends in the experimental test burner manufactured in Mechanical power engineering laboratory at Tanta University, Egypt. Diesel and a mixture of diesel and biodiesel (B0, B10, B20, B30, and B40) used as a fuel with the effect of pure air and oxy‐combustion. Different emission parameters (carbon monoxide, carbon dioxide, unburned hydrocarbons, NOx, and soot opacity) and the flame parameters (flame cone angle and flame length) were also studied. It has been found that the emission parameters and the flame temperature are higher in diesel fuel than diesel and biodiesel blends for pure air combustion and oxy‐combustion. It has also been found that flame parameters (the flame cone angle and flame penetration length) decreased by adding the oxygen into the charged air and increased by increasing the biodiesel mass percentage. The complete combustion of the fuel blends will dramatically increase the flame temperature due to the presence of a sufficient amount of oxygen for the early chemical reaction between fuel and oxidizer. These results indicated that the biodiesel could be the best alternative as well as an environmentally friendly fuel for diesel engines.

A Multi-Platform Lab for Teaching and Research in Active Distribution Networks

Today's electricity paradigm requires that the notion of active distribution systems be introduced at both undergraduate and graduate curricula. This involves not only the customary theoretical foundations but also a suitable power engineering laboratory, where flexible enough and affordable resources allow students and researchers to carry out hands-on experiments reinforcing the concepts explained in the classroom. This paper describes the smart grid laboratory of the Power Engineering Group at the University of Seville, composed of a scaled-down distribution system, along with the required control and monitoring equipment, designed to help its users easily grasp the major influence that distributed generation and storage devices exert in the operation of medium-voltage distribution systems.

Development of a Power Systems Protection Laboratory through University-Industry Partnership

At the 2007 National Science Foundation workshop on ‘The Future Power Engineering Workforce’ participants from US government, academia, and the private sector discussed the looming shortage of power engineering graduates to replace large numbers of projected retirees in the power engineering sector. The group identified the key drivers of this shortage and suggested a series of measures which, if implemented, would add to the ongoing renaissance in power engineering. Some of these measures have been adopted and reflected in the development of a power system protection lab at Penn State Harrisburg. With the support of local utility industry a new lab has been developed that integrates the latest devices and software in the electric utility industry into power systems courses. Instructional modules on key aspects of the new lab are developed to assist both the course instructor and future students enrolled in Power Systems Analysis courses. This paper outlines the facilitation and design process in the development of a modern power engineering laboratory.

Unified Power Engineering Laboratory for Electromechanical Energy Conversion, Power Electronics, and Power Systems

This paper introduces a unified power engineering laboratory capable of various experiments for power systems, power electronics, and electromechanical energy conversion. It presents a flexible hardware setup, data acquisition (DAQ), and virtual instrumentation (VI). Some features of virtual instrumentation are shown with real-time phasor diagrams, sequence component analysis, and spectral analysis of AC data. We describe the general design of a single laboratory setup, which can be used for power electronics and electromechanical energy conversion experiments independently. We also present an example of power system operations, which can be implemented by the interconnection of several laboratory stations.

Distance learning power engineering laboratory

This article features RemoteX, which is an infrastructure to deliver power engineering laboratory experiments as objects over the Internet. It enables instructors, researchers and students to conduct and control actual experiments remotely through the Internet. Real-time relevant waveforms can be shown right in front of students so instructors can explain technical subjects and concepts better. In other words, equipment and instrumentation located elsewhere can be used to assist the classroom teaching of technical courses that are offered at other universities or teaching institutions.

A project-oriented power engineering laboratory

This paper presents a power engineering educational laboratory suitable for undergraduate and graduate students. The laboratory development is based on the new academic system, called "Institut Universitaire Professionnalise (IUP)", initiated in France. The pedagogical approach taken is one where the students revisit previously studied material placed in a practical context. This approach supports the prerequisite lecture material and allows study of some practical issues which are best handled in a laboratory setting. The experimental format gradually puts the students in touch with industrial realities. The laboratory experience culminates in a project, based on a computer aided design (CAD) technique, where the student analyzes, designs, simulates and demonstrates electric machines and power systems related topics.

Transformer design in the undergraduate power engineering laboratory

A power engineering laboratory experiment on transformer design is described. In the experiment the student design, builds, and tests a single-phase transformer to specifications provided by the instructor. From initial test results, the transformer is redesigned, and the new design is tested. Standard open and short-circuit tests are then performed to develop a circuit model for the transformer. The model is then used to predict the transformer's operation, and the predictions are compared with the values measured in the laboratory. >

Electric power engineering laboratory resources of the United States of America and Canada

The authors present the result of a study of the state of electric power engineering laboratory resources of 123 educational institutions in the United States and Canada. The study deals with five principal areas: basic demographic information; equipment available to the student researcher; educational and experimental emphasis in the power area; areas of research done in the power laboratory; and opinions, planning, and interests of students and faculty members. It is found that 78% of the respondents regard a power laboratory as important for their students' education, and yet 83% still place an emphasis on component-oriented experiments which do not give the students adequate preparation for the system aspect often encountered on the job. Furthermore, 84% agree that the education of power engineers relies too heavily upon computer simulation studies, and should be complemented with work on physically based laboratory systems. >
