boundary condition in combustion model
I'm dealing with combustion modeling.The boundary conditions of the model are(the field is rectangular):
to solve the momentum equation,the pressure is given at the outlet and the velocity is given for th inlet
to solve the temperature equation the values are given for the inlet,left and right;the gradient is fixed for the outlet,
for the momentum I tried this for the pressure
value uniform (value);
for the left and right it is also 'calculated'
for the velocity
the others are uniform
But it seems like it doesnt work,I came out with an error!!!
Can somebody help me out?
and how to implement the fixed gradient for the temperature? I did
gradient (value of the gradient);
but it didnt work either!!
Please, I need your help
