SYMPTOM:
Incorrect values of laminar burning velocity can be obtained from the Solver for certain conditions. This will lead to either a discontinuity of the burning velocity, which can be observed in CFX Post, or to blow-out of the flame.
PROBLEM:
There are errors in the coding for equivalence ratios that are inside the 'Flammability Limits' and outside the 'Fit Range'. The following options are affected by the issue: the "Metghalchi and Keck" option for Laminar Burning Velocity and the "Quadratic Decay" and "Fifth Order Polynomial" options for Equivalence Ratio Correlation/Reference Burning Velocity.
|
WORKAROUND: Either specify the Laminar Burning Velocity in CEL or use the "Beta Function" option for Equivalence Ratio Correlation/Reference Burning Velocity. FIXED IN: ANSYS CFX Release 11.0 Update 1. |
