Aerodynamics
The expansion ratio is a critical parameter that quantifies the change in area or volume of a fluid as it undergoes an expansion process, often in the context of gas dynamics. In the realm of supersonic flow, it specifically refers to the ratio of the exit area to the throat area of a nozzle, impacting the flow speed and pressure characteristics significantly. Understanding the expansion ratio helps in analyzing flow behavior through expansion waves and is essential for designing efficient aerodynamic systems.
