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