IMECE2008-66948 PROCESS TECHNOLOGY CONCERNING THE COUPLED SOLID-LIQUID INDUSTRIAL WASTE COMBUSTION FOR THE PAPER INDUSTRY

ABSTRACT The paper present the research concerning technical possibilities to tamp the solid industrial waste coming out from an already refurbished paper plant in Adjud, Romania, in order to reduce the overall costs of the necessary landfill deposits and to create a real income by producing energy . An infrared system of a FLIR S65 videocamera (7-14 µm) and double wave length OMEGA OS3750 pyrometer (0.9 -1.5 µm) have been used in order to assess the best thermal regime to ignite and to control the burning process of the industrial refuse

Schlieren image velocimetry methods for a round, hot, turbulent air-jet

The present article investigates the accuracy of measurements regarding the velocity profile of a turbulent jet. The measurements are obtained by applying image processing techniques to schlieren methods. The schlieren methods described here are relatively new, having been patented and used for the first time in the last few years. Generally, SIV methods applied to turbulent flows result in unrelatable/ unrelated data, given the path-integrated nature of the flow. The global measurement errors and ways to reduce them are also discussed

The Influence of Motivational Factors on the Performance in the Research Activity

In the present study, the motivational factors refer to all those factors that are associated with the researchers’ motivation and which have an influence on increasing the RDI activity performance. Consequently, the context is defined by the RDI activity, by the way it is organized and by the conditions under which the activity is carried out. Two categories of motivation were analyzed: intrinsic and extrinsic motivation. Performance in RDI occupations refers to the performance of the research staff. The present research aimed to analyze the influence of the motivational factors on the performance of RDI research staff. The results show that motivation plays an important role in increasing performance in RDI occupations. The mean values for intrinsic motivation are higher than those obtained for extrinsic motivation (mean factor of 4.27 versus 3.81)

Advancing Research Data Management in Universities of Science and Technology

The white paper ‘Advancing Research Data Management in Universities of Science and Technology’ shares insights on the state-of-the-art in research data management, and recommendations for advancement. A core part of the paper are the results of a survey, which was distributed to our member institutions in 2019 and addressed the following aspects of research data management (RDM): (i) the establishment of a RDM policy at the university; (ii) the provision of suitable RDM infrastructure and tools; and (iii) the establishment of RDM support services and trainings tailored to the requirements of science and technology disciplines. The paper reveals that while substantial progress has been made, there is still a long way to go when it comes to establishing “advanced-degree programmes at our major universities for the emerging field of data scientist”, as recommended in the seminal 2010 report ‘Riding the Wave’, and our white paper offers concrete recommendations and best practices for university leaders, researchers, operational staff, and policy makers. The topic of RDM has become a focal point in many scientific disciplines, in Europe and globally. The management and full utilisation of research data are now also at the top of the European agenda, as exemplified by Ursula von der Leyen addressat this year’s World Economic Forum.However, the implementation of RDM remains divergent across Europe. The white paper was written by a diverse team of RDM specialists, including data scientists and data stewards, with the work led by the RDM subgroup of our Task Force Open Science. The writing team included Angelina Kraft (Head of Lab Research Data Services at TIB, Leibniz University Hannover) who said: “The launch of RDM courses and teaching materials at universities of science and technology is a first important step to motivate people to manage their data. Furthermore, professors and PIs of all disciplines should actively support data management and motivate PhD students to publish their data in recognised digital repositories.” Another part of the writing team was Barbara Sanchez (Head of Centre for Research Data Management, TU Wien) and Malgorzata Goraczek (International Research Support / Data Management Support, TU Wien) who added:“A reliable research data infrastructure is a central component of any RDM service. In addition to the infrastructure, proper RDM is all about communication and cooperation. This includes bringing tools, infrastructures, staff and units together.” Alastair Dunning (Head of 4TU.ResearchData, Delft University of Technology), also one of the writers, added: “There is a popular misconception that better research data management only means faster and more efficient computers. In this white paper, we emphasise the role that training and a culture of good research data management must play.

New energy value chain through pyrolysis of hospital plastic waste

International audienceIn this paper, the evolution in thermochemical behaviours of hospital plastic wastes and changes in chemical composition and characteristics of pyrolysis liquid products have been investigated by using different fixed bed reactor scales. The main objective is to identify the critical technical parameters enabling thermochemical process adaptation in function of raw materials chemical structure, with the aim of maximising the yield of condensable fraction and optimising its energetic properties related to internal combustion engines. It is a step-by-step procedure using three reactor capacity levels, which allows various aspects approach of thermochemical process development from the evaluation of global reaction kinetic parameters to the measurement of physicochemical properties of the final pyrolysis products. In order to reduce the gas and solid fractions with corresponding increasing of condensable products, the transposition of thermal and kinetic information provided by thermogravimetric analysis (TGA) to larger reactors is used to control of process parameters. In this experimental work the mass of samples increases from 0.05 g in the thermogravimetric analyser to 600 g in the bench scale reactor. Gas-chromatography techniques have been used to identify the chemical composition of gases (GC/TCD) and liquids (GC/FID-MS). It was established that changing the reactor scale does not result in significant differences in pyrolysis product distribution, neither in gas composition. On the other hand, the aspect and the quality of condensable fraction display a high variability. Also, the energy contained in the final valuable pyrolysis product was compared with the energy demand during the thermochemical transformation in order to evaluate the energy efficiency of the process.

Energy and exergy analysis of a flat plate collector using collector test equations

This paper presents the energetic and exergetic analysis of a widely used flat plate collector based on the collector testing equations. The evaluation of the performances of the collector is done under the climatic conditions corresponding to a typical meteorological year in Constanta, Romania. Using a dimensionless-geometric optimization criterion, the climatic conditions for which the energy efficiency and exergetic efficiency have the maximum values are determined. The optimal weather conditions for the collector's operation are: the solar irradiation of 916 W/m2 and the air temperature of 15.4 °C; under these conditions, the energy and exergy efficiencies of the collector are 57% and 4.8%, respectively
