In a context of energy abundance for industrial applications, industrial systems are exploited with minimal attention to their actual energy consumption requirements to meet the loads imposed on them. As a result, most of them are used at maximal capacity, regardless of the varying operational conditions. First, the paper studies pneumatic conveying systems and thoroughly reviews previously published work. Then, we overview simulations and operating data of the experimental parameters and their effects on the flow characteristics and transport efficiency. Finally, we summarize with a conclusion and some suggestions for further work. The primary goal of this study is to identify the parameters that influence the energy consumption of industrial dust collector systems. It is differentiated from previously published overviews by being concentrated on wood particles collection systems. The results will permit a better selection of an appropriate methodology or solution for reducing an industrial system’s power requirements and energy consumption through more precise control. The anticipated benefits are not only on power requirement and energy consumption but also in reducing greenhouse gas emissions. This aspect shows more impacts in regions that rely on electricity supplied by thermal power stations, especially those that use petrol or coal.
Service learning is a very interesting pedagogical approach for engineering education. It can be used in most engineering courses, but it fits well in a project-based design course. Through service learning, the students work with a real customer, apply all the steps of the design cycle, deliver a functional prototype, manage a real project, understand the multi-faceted responsibilities of an engineer and develop team work and communication skills. The approach was introduced in an existing, first year, first semester, design course. The experience shows that projects can be found in the community without too much effort, students perform very well and can deliver functional and useful prototypes in four months. Before introducing the service learning approach, the course was already well evaluated and is even more appreciated now. The conclusion is that service learning is a perfect approach for a course that was designed to introduce students to real-world problems in engineering at the start of their engineering education.
In undergraduate engineering programs, design competency is mainly developed through project-based design courses. In such courses, a well framed practice is one of the best strategy to help students develop the ability to design solutions to complex, multifaceted and open-ended engineering problems. Nevertheless, supervising students, especially first-year students, requires a lot of effort and time. As the number of students increases, the task of closely supervising them becomes more difficult. Considering the small number of academic staff, peer tutors can provide a solution to the lack of resources. In addition to this, peer-tutoring is a very interesting pedagogical solution. In fact, the literature demonstrates that peer tutoring can benefit both students and tutors.Teaching assistants (TAs) have contributed in project based courses for a long time but there are not so many documented experiences about how to integrate peer-tutoring in a project-based design course or how to use fourth year students to tutor first year students.In fall 2017, a peer-tutoring program (PTP) has been implemented in the first year multidisciplinary design course. Fourth-year engineering students with relevant design experience acted as tutors for teams of four or five students. The intention was to reduce the pressure on our professional staff, while maintaining the same quality level of supervision.PTP assessment revealed that all stakeholders appreciated the experience. At low cost, it allowed more weekly hours of supervision and gave the professionals the possibility to perform tasks that only them can do. Although the impact of PTP on the quality of learning was not measured, the student level of satisfaction was very high.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
