Hi everyone,

I build a model that the fuel is injected from the surface of a circle and I want to use rhoreactingBuoyantFoam to solve the process. However, when the product reached the boundaries, the pressure and temperature will decrease sharply. I am wondering whether it is the problem of boundary condition.

The first and second is the pressure and temperature at 2.3s. The ambient pressure is about 2.9e4Pa and the temperature is 200K, which are abnormal.

The attachments are the boundary conditions for p, p_rgh, and T.

For other boundary conditions, I use

    "(top|bottom|inlet|outlet)"
    {
        type            inletOutlet;
        inletValue      $internalField;
        value           $internalField;
    }

for the four boundaries.

Could anyone help me figure out the reasons?

Thank you so much!
