(3) Distribution of Temperature Field
Figure 10.17 shows the temperature distribution in the Laval nozzle. The temperature of gas in Laval nozzle changes continuously when it flows, and the temperature of gas decreases continuously throughout the nozzle. The average temperature
at the entrance is set to 600 K. The airflow passes through the Laval nozzle, and the
average temperature at the exit decreases to 210 K.
Figure 10.18 shows the temperature variation of Laval nozzle wall. The temperature at the entrance wall is 610 K. As the gas passes through the Laval nozzle,
