You must — there are over 200,000 words in our free online dictionary, but you are looking for one that’s only in … The flamelet concept considers the turbulent flame as an aggregate of thin, laminar (Re < 2000), locally one-dimensional flamelet structures present within the turbulent flow field. Counterflow diffusion flame is a common laminar flame which is used to represent a flamelet in a turbulent flow. Its … See more The laminar flamelet model is one of the methods of modelling turbulent combustions apart from SCRS, eddy flamelet model and others. Combustion is a very important thermochemical process with significant … See more The disadvantages of Steady Laminar Flamelet model due to above mentioned reason are: 1. It does not account for the curvature effects which can change the flame structure and is more detrimental while the structure hasn’t … See more To model a non-premixed combustion, governing equations for fluid elements are required. The conservation equation for the species mass fraction is as follows:- See more The advantages of using this combustion model are as follows: 1. They have the advantage of showing strong coupling between chemical reactions and … See more 1.
