flamethicklinthermcrestb

algorithm

  • batch modus of flamethicklinthermcrest
  • calculates thickness of a flame between user defined boundaries
  • defined by the maximum temperature gradient along linear cuts through flame front
  • flame is defined as crestline of user defined variable
  • plots flame thichkness vs. curvilinear coordinate of flamefront;
  • calculates minimum-, maximum- and mean thickness
    flamethickn 

syntax

[siso,flthickth300,maxfl,minfl,meanfl]=flamethicklinthermcrestb(X,Y,varbaund,CRESTN,variable,s,iso1,iso2) 

 

example for input

[siso,flthickth300,maxfl,minfl,meanfl]=flamethicklinthermcrestb(X,Y,Z,CRESTN,TEMP,'abs',0.9,0.1) 

 

input arguments

Name description

s switch (choose level, iso1,iso2 is rel. or absolut)
variable temperature
iso1, iso2 isolevels defining boundaries of flame front (e.g. 0.9, 0.1)

output arguments

Name description
