Hi,

I tried to simulate a hypersonic flow through a scram-jet engine in rhoCentralFoam but a Normal shock is getting generated as you can see that in the attached picture. Same thing is happening when I tried to use sonicFoam. I really don't know the reason, Please help.
the BC are

pressure:
internalField uniform 139.81;

boundaryField
{
inlet
{
type fixedValue;
value uniform 139.81;
}

outlet
{
type zeroGradient;
}
............................

temperature:
internalField uniform 123.12;

boundaryField
{
inlet
{
type fixedValue;
value uniform 123.12;
}

outlet
{
type zeroGradient;
}
......................

velocity:
internalField uniform (0 0 0);

boundaryField
{
inlet
{
type fixedValue;
value uniform (1778.711 0 0);
}

outlet
{
type zeroGradient;
}
...............

Thanks

Regards,
Ishan
