flamethicknonlincrest
algorithm
- calculates thickness of a flame between user defined boundaries
- in a single user defined point
- as extension of a non linear cut through flame front
- the flame is defined by the crestline of a user defined variable
- the cut is defind by the gradients of varbound
- for batch modus along crestline use flamethicknonlincrestb
syntax
[flthick]=flamethicknonlincrest(X,Y,xs,ys,varbound,CREST,s,iso1,iso2)
example for input
[flthick]=flamethicknonlincrest(X,Y,0.0045,0.0024,Z,CREST,'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) |
| varbound |
variable defining the boundaries of the flame front |
| CREST |
coordinates of crestline |
| s |
switch (choose level, iso1,iso2 is rel. or absolut) |
| iso1, iso2 |
isolevels defining boundaries of flame front (e.g. 0.9, 0.1) |
