flamethickc
flamethickc
algorithm
- calculates thickness of a flame based on reaction progress variable
- between c=0.01 and c=0.99;
- 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 flamethickcb
syntax
[flthick]=flamethickc(X,Y,xs,ys,nxs,nys,fdefine,c,level,s)
example for input
[flthick]=flamethickc(X,Y,0.0041,0.0055,0.7413,0.6711,Y_OH_,c,0.6,'rel')
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. or absolut) |
| c | reaction progress variable) |
output arguments
| Name | description |
|---|---|
| flthick | thickness of a flame between user defined boundaries |
| plot | cut along thickness is calculated |
