A vortex generator system has at least two vortex generators protrudable from an outer mold line of a vehicle surface at a location upstream of a cavity leading edge of a cavity in the vehicle surface. The vortex generators are spaced apart from each other and oriented such that the vortex generator aft ends are nearer to each than the vortex generator forward ends. The vortex generator lengthwise direction of each one of the vortex generators is oriented at a vortex generator directional angle relative to a direction of an airflow. The vortex generators are configured to generate a pair of counter-rotating vortices when the airflow passes over through or over the vortex generators. The counter-rotating vortices interact to produce a downwash of air away from the cavity that urges the store away from the vehicle as the store exits the cavity.

Concepts and technologies are disclosed herein for modeling propulsion-related interfaces in computational fluid dynamics ('CFD'). According to some embodiments disclosed herein, a model is obtained or developed and propulsion-related interfaces within the model are identified. Flow directions of velocities, temperature, and/or mass are calculated adjacent to the propulsion-related interface and compared. A mass flow rate, a conserved variable state jump, a change in flux across the interface, and/or incoming and outgoing flux values can be calculated for the propulsion-related interface. The calculated values can be returned and embedded in the model. The model is solved and a solution is output.
