• Resumen

  • The proper scaling of the pressure�velocity coupling that arises from the momentum interpolation approach for unsteady calculation in low Mach number flow is first identified.

    Then, it is used to suggest a modification of the AUSM+-up scheme that allows acoustic simulations in low Mach number flow.
