flamethicknonlinbtherm

algorithm

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

syntax

[sisok,flthick,maxfl,minfl,meanfl]=flamethicknonlinbtherm(X,Y,fdefine,level,s,variable,iso1,iso2) 

 

example for input
