Gulders flame speed correlation
 

Hello,

There seems to be an issue with the implementation of the Guelders flame speed correlation. The issue affects simulations where there is a pure fuel and pure oxidizer inlet. The Problem can be reproduced with the Xoodles solver and the Pitz and Daily 3D test case. To break it set:

thermoType hhuMixtureThermo<inhomogeneousMixture<sutherlandTr ansport<specieThermo<janafThermo<perfectGas>>>>>;

and

in 0/ft

internalField uniform 0.05;

boundaryField
{
inlet
{
type fixedValue;
value uniform 1.0;
}
.......

then start a reacting simulation. First time the Guelders correlation is called the code breaks.

Now fixed in 1.5.x.
