In the section containing formulas, the terms need to be defined explicitly. Even scientifically-literate readers have no way of knowing what these symbols mean unless they are already familiar with such methods. --Sammy1339 (talk) 01:40, 7 November 2014 (UTC)[reply]
By the way, aside from the spacing issues and odd reference locations, this article is very poorly written from a basic grammar POV. 136.49.32.166 (talk) 15:03, 19 August 2021 (UTC)[reply]
Wikinetic removed some text. His action was reverted by Sakura emad (who doesn't really edit but just goes around reverting other people's edits).
Just trying to develop some consensus that the removals are legit. (I'm inclined to agree with Wikinetic based on the poor quality of the "sources", they're rather outdated.) 136.49.32.166 (talk) 18:33, 18 August 2021 (UTC)[reply]
Assumptions
The following assumptions are made in the study of all the flamelet models:[1]
1. While modelling only a single mixture fraction are allowed. Modelling of two-mixture-fraction flamelet models is not possible.
2. It is assumed that the mixture fraction follow the β-function PDF, and scalar dissipation fluctuations are not considered.
3. Empirically-based streams cannot be used.
Disadvantages
The disadvantages of Steady Laminar Flamelet model due to above mentioned reason are:[2]
1.It does not account for the curvature effects which can change the flame structure and is more detrimental while the structure hasn’t reached the quasi-steady state.
2.Such transient effects also arise in turbulent flow, the scalar dissipation experience a sudden change. As the flame structure take time to get stabilize.
To improve the above SLFM models, few more models has been proposed like Transient laminar flamelet model ( TLFM) by Ferreira .
