For a dump diffuser system, the characte ristics of pressure is governed by several geometric and flow parameters, including pre diffuser length and area ratio; the dump gap and expansion ratio; the airflow splits between the dome and the inner and the outer annuli; and the velocity distribution at the compressor exit.
