Detailed Description

This boundary condition provides a supersonic free-stream condition.

- supersonic outflow is vented according to ???

  • supersonic inflow is assumed to occur according to the Prandtl-Meyer expansion process.
  • subsonic outflow is applied via a zero-gradient condition from inside the domain.
Usage
Property Description Required Default value
T Temperature field name no T
p Pressure field name no p
psi Compressibility field name no thermo:psi
UInf free-stream velocity yes
pInf free-stream pressure yes
TInf free-stream temperature yes
gamma heat capacity ratio (cp/Cv) yes

Example of the boundary condition specification:

    <patchName>
    {
        type            supersonicFreestream;
        UInf            500;
        pInf            1e4;
        TInf            265;
        gamma           1.4;
    }

Note: This boundary condition is ill-posed if the free-stream flow is normal to the boundary.
