flamethicklin

algorithm

  • calculates thickness of a flame between user defined boundaries
  • as length of a linear cut through flame front
  • the cut starts in a user defined point;
  • for batch modus along curvilinear coordinate of flame front use flamethicklinb
    thicklincut2d 

syntax

 [flthick]=flamethicklin(X,Y,xs,ys,nxs,nys,fdefine,level,s,iso1,iso2) 

 

example for input

 [flthick]=flamethicklin(X,Y,0.0052,0.0044,0.7642,-0.6468,Z,0.5,'abs',0.9,0.1) 

  

input arguments

Name description
X,Y vectors defining the rectangular domain
XS,YS coordinates of starting point of the cut (only for one point modus)
NXS,NYS components of normal vector defining the direction of the cut
fdefine variable defining the flame front
level isovalue of fdefine defining the flame front
s switch (choose level, iso1,iso2 is rel(ative). or abs(olut))
iso1, iso2 isolevels defining boundaries of flame front (e.g. 0.9, 0.1)

output arguments

Name description
flthick thickness of a flame along a linear cut between user defined boundaries
plot cut along thickness is calculated
