intcutlin

algorithm

  • returns the integral value of a variable along a single linear cut across the flame front
  • the cut is determined using the tool lincut
  • the integral uses the values of variable and
    the values of the gradient of fdefine along the cut
    and the matlab tool trapz for the integration
  • plots the cut and variable along the cut
  • for batch modus along curvilinear coordinate of flame front use intcutlinb

syntax

intvar=intcutlin(X,Y,XS,YS,NXS,NYS,fdefine,variable,dl,level,s,iso1,iso2) 

 

example for input

intvar=intcutlin(X,Y,0.0052,0.0044,-0.7627,0.6468,Z,temperature,0.00005,0.5,'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
NXS,NYS components of normal vector defining the direction of the cut
dl steps between two iterations
fdefine variable defining the flame front
variable variable to be extracted along the cut
level isovalue of fdefine defining the flame front
s switch (choose level, iso1,iso2 is rel. or absolut)
iso1, iso2 isolevels defining boundaries of flame front (e.g. 0.9, 0.1)

output arguments

Name description
intvar integralvalue of variable along the cut
plot cut, variable along cut
