SimScale Simulation: Drop shape, Run 1. Entry speed 7m/s, red zone 9.4m/s

SimScale Simulation: Drop-Ring shape, Run 1. Entry speed 7m/s, red zone 11.66 m/s Ring with nozzle / diffuser geometries.

SimScale Simulation: flat dome Drop-Ring shape, Run 6. Entry speed 7m/s, red zone 12.41 m/s Ring with smaller entry larger exit geometries. Less disturbance than before.

Result in 1 m/s higher speed through the ring area and higher speed on the dome side.

Lower area of slower entry speed (green).
