 Definition A sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat or both heat and light in the form of either a glow or flames. [d] [e]


As one of the major contributors to the Wikipedia article on Combustion which was transferred here by Graham Proud, I plan to go through it and edit it fairly completely to turn it into a CZ article. As with many articles in Wikipedia, it grew in a topsy-turvey manner with various people contributing their own small parts with very little attempt to format the overall article into a coherent whole. So I will probably be deleting certain parts which don't seem germane to me. If anyone disagrees with any of my edits, please feel free to tell me so here on this Talk page and we can work out an agreeable version. Thanks, - Milton Beychok 18:58, 18 June 2008 (CDT)

Need help with the Rayleigh criterion

The section of this article that discusses combustion instabilities has as equation referred to as the "Raleigh Criterion". Is anyone familiar with that equation? If so, please define each of the variables in the equation ... and perhaps add some discussion as well. Thanks on advance, - Milton Beychok 22:08, 18 June 2008 (CDT)

The section on Instabilities that included the "Rayleigh Criterion" has now been deleted. See posting just below. Milton Beychok 22:26, 12 March 2010 (UTC)

Extensive revisions

I have made some extensive revisions to this article to improve it, including:

  • Revised all of the LaTeX math chemical reactions to bold font HTML which looks much better in the context of this article. Now all of the chemical reactions are consistent in appearance ... before some were HTML and some were LaTeX mat.
  • Numerous typos were corrected.
  • Added an image for the section on "Smouldering combustion".
  • Added a number of additional references. (There was only one reference before.)
  • Deleted the section on "Instabilities" completely because, in my opinion, it really belongs in an article about rocket engines rather than here.
  • Deleted the section on "Reaction mechanism" completely because, in my opinion, it was much too technical. I didn't understand it myself and I doubt if our intended audience would understand it.

I made all of the above edits in a copy of the article in my sandbox and then replaced the article completely with my sandbox copy. Thus, the History will not show numerous edits ... but will show just one big revision. Milton Beychok 22:23, 12 March 2010 (UTC)
