strainratelev
algorithm
- first calculates (normal and tangential) strain rate values in a 2d field
- then extracts values of strain rate along user defined flamefront
syntax
[siso,strnff,meanstrn,strtff,meanstrt]=strainratelev(X,Y,xvel,yvel,fdefine,level,s)
example for input
[siso,strnff,meanstrn,strtff,meanstrt]=strainratelev(X,Y,x_velocity,y_velocity,Y_OH_,0.5,'rel')
input arguments
| Name | description |
|---|---|
| X,Y | vectors defining the rectangular domain |
| x_velocity, y_velocity |
velocity components |
| fdefine | variable defining the flame front |
| level | isolevel defining the flame front |
| s | switch between absolut and relativ for level |
output arguments
| Name | description |
|---|---|
| siso | curvilinear coordinate of flame front |
| strnff, strtff | values of strain rate along curvilinear coordinate of flamefront |
| meanstrn,meanstrt | mean values of normal and tangential strain rate |
| plots | normal and tangential strain rate along flame front |
