When the airflow passes through Laval nozzle, its special shape will cause a series of amazing changes. In the contraction section, the airflow gradually converges, and the speed and pressure increase continuously, as if it were a thrilling adventure. In the expansion section, the airflow is like a runaway wild horse released, which expands rapidly and gallops out at supersonic speed.
Laval nozzle design is a perfect combination of science and art, and the shape and proportion of contraction section and expansion section are like musical instruments in musicians' hands, playing gorgeous movements at supersonic speed. This ingenious design makes the airflow get the best acceleration effect in the nozzle, and avoids the phenomenon of airflow separation and instability.
