Supersonic outlet boundary condition

    • Abubakar

      Hi sir,

      I have a question related to outlet boundary condition for supersonic flow.

      What I have a read is in supersonic flow static pressure can't propogate back Upstream faster then wave speed so, I didn't understand this statement can anyone explain me this thing in brief? TIA

      Yes , for supersonic outlet conditions, the static pressure at the outlet is extrapolated from interior cells. So the specified pressure will no longer be used. The reason for this is as you have mentioned already.

      At supersonic inlet you specify everything at supersonic outlet nothing you specify will be used.
