flamefront

algorithm

• plots flamefront based on a user defined variable
  (e.g. mixture fraction or mass fraction of a radical)
• and a user defined isolevel of this variable
• and optionally user defined boundaries of flamefront
• using the matlab tool contour

 

syntax

[og,ug]=flamefront(X,Y,fdefine,level,s,iso1,iso2) 

<br>

example for input

[og,ug]=flamefront(X,Y,Z,0.5,'abs',0.9,0.1) 

 

input arguments

Name	description
X,Y	vectors defining the rectangular domain
fdefine	variable defining the flame front (e.g. Z)
level	isolevel of fdefine defining the flame front (e.g. 0.5)
s	switch (choose s='abs' if level, iso1,iso2 is absolut s='rel' if level, iso1,iso2 is relativ
iso1,iso2	isolevels defining boundaries of flame front (e.g. 0.9, 0.1)

 

output arguments

Name	description
og, ug	boundaries of flamefront
plot	isolevel of flamefront, optionally isolevels of boundaries
