成人大片

The International Sooting Flame (ISF) Workshop is an ongoing, biennial forum. It was held from 18 - 20 January 2021, timed to occur before the , 24 - 27 January 2021, both to be based in Adelaide, South Australia.

Organised by researchers, for researchers, to develop improved predictive capability of soot in flames of practical relevance through international collaboration between experimentalists and modellers. It is an open forum held immediately prior to each meeting of the International Symposium on Combustion.

A program is now available to download.

More details are available here and have been sent to the ISF mailing list.

ISF-5 Poster/Video presentations

Attendees of ISF-5 were invited to create a poster presentation to share at the virtual meeting.

They were asked to provide a short presentation in the format of a 3 slide PowerPoint MP4 recording of 2-5 minutes duration that was no more than 20MB in size.

Poster presenters were also asked to provide a Zoom link on their presentation to allow for a question and answer session, after the video had been played at the workshop.

A link to a 成人大片 Box folder was sent to all, who registered to present a poster/video at ISF-5.

By uploading a short video to the Box folder, participants agreed to share the content of their work on the ISF web page.

Participants were instructed to consider the content, ensuring that they did not share details of their work that was commercial-in-confidence, and that they acknowledged the source of any material that they shared that was subject to copyright.

All content was to be uploaded to the Box folder by Monday January 11, 2021.

• To advance understanding and predictive capability of flames with soot, to identify gaps in this understanding and to coordinate research programs to address them;
• To identify well defined target flames and coordinate additional experiments that provide suitable data for model development and validation, spanning a variety of flame types and fuels in each of the research programs;
• To establish an archive of the detailed data sets of target flames with defined accuracy and to provide a forum for the exchange and dissemination of these data;

Objective 1

To advance understanding and prediction of inception-dominated ethylene flames:

• Target 1: obtain new systematic data in inception-dominated laminar ethylene flames (such as counter-flow flames) to achieve conditions for key controlling parameters (such as residence time) that better match those that apply in the existing data sets for turbulent ethylene jet target flames. Data is sought for both atmospheric and elevated pressure conditions.

Objective 2

To advance prediction of sooting flames in the growth/agglomeration regimes of ethylene flames:

• Target 2: obtain new systematic data in growth/agglomerated-dominated regimes of turbulent ethylene flames (such as the recirculation region of bluff-body flames) to achieve conditions for key controlling parameters such as residence time that better match those that apply in the existing data sets for laminar ethylene jet flames. Data is sought for both atmospheric and elevated pressure conditions.

Objective 3

To advance prediction of sooting flames with more practical fuels:

• Target 3: establish a coordinated data base, building on existing data, in the laminar and turbulent regimes, and at a range of pressures, for methane flames and pre-vaporised heptane flames;

Objective 4

To engage with the international community through a joint session with members of the flame chemistry workshop to develop better understanding and models of soot evolution, addressing both:

• PAH chemistry, soot inception, and
• soot oxidation

The workshop is organised around the following two Research Programs, each spanning a range of temperatures and pressures:

• Laminar flames: Chemical Kinetics (PAH, inception, growth and oxidation); particle dynamics (moment methods, sectional models, coalescence vs. aggregation), shock tubes;
• Turbulent flames: Jet flames, bluff body flames, swirl flames, pool fires; influence of scale;

In 2021, the ISF Workshop meeting was conducted virtually, and featured an online video poster presentation.
