“…In this way, the odd-carbon-atom pathway of the cyclopentadienyl radical dimerization to form naphthalene [reaction (R2)], has been proposed in the 165 literature (e.g., Castaldi et al, 1996;Marinov et al, 1996): Figure 3 reports the total soot amount collected (in g) and the soot yield (in %), in all of the experiments. The soot yield is defined as the percentage of the carbon amount in soot related to the carbon amount fed into the reactor (Esarte et al, 2009).…”

The sooting tendency of 2,5-dimethylfuran (2,5-DMF), as a proposed fuel or fuel additive, has been studied in a flow reactor at different reaction temperatures (975, 1075, 1175, 1275, 1375, and 1475 K) and 10 inlet 2,5-DMF concentrations (5000, 7500, and 15,000 ppm) under pyrolytic conditions. The quantification of soot and light gases has been done. Additionally, the experimental results of the light gases have been simulated with a detailed gas-phase chemical kinetic model. The experimental results indicate that the temperature has a 15 great influence on both the soot and gas yields, as well as on the concentration of the light gases of pyrolysis. The inlet 2,5-DMF concentration influences the soot yield, whereas no significant effect is observed on the gas yield.ARTICLE HISTORY

“…The rich-C2H2 flame (0=2.40) was also an MBMS study at low pressure (20 torr). The results of the simulation were acceptable for the main species, especially for the fuel decay.Comparisons have been also made with the experimental data reported by Castaldi et al (1996) and their predictions, presented in the same paper. That flame is not a low-pressure flame (P=l arm) and would be a good test for our model developed initially for low-pressure systems.…”

“…As experimentalists, we recognize that data always have some degree of error. However, modeling may reveal errors and room for improvement in reaction sets and physical models.The experimental data considered were mainly flat flames of C2H4: very lean (0=0.21) by Peeters and Mahnen (1973), lean (0=0.75) by Bhargava (1997Bhargava ( , 1998b, rich (0=1.90) by Bhargava (1997Bhargava ( , 1998a, and very rich (0=3.06) by Castaldi et al (1996). A rich C2H2 flame (0=2.40) by Westmoreland (1986) was also used to assess the validity of the mechanism.…”

Roberts, principal investigator PERFORMING ORGANIZATION NAME(S) AND ADDRESS(bS)North Carolina State University Raleigh, NC 27695-7514 SPONSORING / MONITORING AGENCY NAMfc(S) AND ADDRESS(bS)U ABSTRACT (Maximum 200 words)Experts assembled in the field of combustion science in order to provide a forum for exchange of research results, foster interactions among research groups, and to speed technology transfer.The Eastern States Section of the Combustion Institute held its Fall Technical Meeting in Raleigh, NC in October 1999. It brought together researchers from ^ government, industry and academia. Combustion science is central to the Army s development of advanced gun, rocket and vehicle propulsion systems. BanquetThe Meeting Banquet will be held on Tuesday Evening at the Velvet Cloak Inn with a "no-host" reception starting at 6:00 pm and dinner being served at 7:00 pm. Lab TourA Tour of the Applied Energy Research Laboratory at North Carolina State University will be arranged starting at 1:30 pm on Wednesday, October 13. Transportation will be provided from the meeting hotels. A sign up sheet will be available during the meeting. Institute! We hope that you find the meeting productive and enjoyable. Our section's format consciously encourages presentation and discussion of new results, especially by promoting the participation of student presenters. Chemical and Physical Processes of CombustionIn addition to the technical program, we have also arranged for the traditional welcoming reception on Sunday night; a barbeque lunch (North Carolina BBQ!) and reception on Monday;and the traditional banquet. These events should help us maintain the collegial atmosphere that we value so much at our Fall Technical Meetings.We are grateful for local sponsorship of this meeting by North Carolina State University and for all the contributions of time, facilities, and other resources toward the success of this meeting.The 28th International Symposium on Combustion will be held on July 30-August 4, 2000, in Edinburgh, Scotland (http://www.efm.leeds.ac.uk/edin2000/). As in 1998, we will not have a 65.66. 67.68. 69. 70.71. The Department of Energy (DOE) has recognized the need to make significant improvements to the overall thermal efficiency of coal-burning plants, while decreasing their environmental impact. Of all the proposed options for future plants, the highest efficiencies are achieved by using Brayton cycles (gas turbines) rather than exclusive reliance on Rankine cycles (steam turbines). The DOE then initiated the research effort for a High Performance Power Generating System (HIPPS), which utilizes gas turbines but excludes all coal combustion products from the working fluid, thus avoiding the expense of hot gas cleanup and/or the corrosion of turbine blades by coal ash. The specific goals for the HIPPS program are shown in Table 1. • Based on 90% reduction of...

Abstract. This article is addressed to a scientific community familiar to astrophysics, and most researchers are not familiar with combustion science. Thus the goal is to provide a basic understanding of "the flame" and the different steps that lead to soot particle formation in conditions that are generally close to atmospheric pressure and high temperature, i.e. in conditions far from those encountered in most astrophysical media. Some experimental techniques of sooty flame investigations will also be introduced. The main aim is to outline the concepts and the tools of combustion science to facilitate fruitful scientific exchanges between two communities that are motivated by the understanding of the formation and evolution of PAHs and soot-like particles, in completely different environments. It should be noted that the description does not pretend to be exhaustive at all and certain theoretical and experimental approaches are not described nor even mentioned.Résumé. Cet article s'adresse à une communauté «astrophysique» non familière avec la combustion. Il a pour but de donner quelques bases permettant de comprendre «la flamme» et les étapes chimiques principales conduisant à la formation de particules de suie dans un milieu généralement à pression atmosphérique et haute température, c'est-à-dire dans des conditions de pression et température très éloignées de celles rencontrées dans le milieu interstellaire. Certaines méthodes expérimentales d'investigation de flammes suitées sont également présentées. L'objectif étant de pouvoir jeter des ponts entre deux communautés éloignées mais rassemblées par un même intérêt pour les hydrocarbures aromatiques polycycliques et les particules de suie. Il est clair que la présentation qui est faite ici est très succincte et qu'elle fait l'impasse sur certaines théories, approches, méthodes expérimentales. . .
