Resumen de Pressure-velocity coupling for unsteady low Mach number flow simulations: An improvement of the AUSM+-up scheme

Yann Moguen, Erik Dick, Jan Vierendeels, P. Bruel

• 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.
