compressible/incompressible flow
1. Consider a typical air flow around a cruising jetliner at
10km altitude. The speed is now 810 km/h, while the
ambient conditions are 0.414 kg/m³, 0.261 atm and
-50°C. At the stagnation point, the temperature rises
over by 25°C, while the density and pressure changes by
more than 30% and 45 % respectively.
2.
Consider a car at sea-level, 1 atm and 15°C, going at a
speed of 90 km/h. The density is 1.225 kg/m³ . At a
stagnation point, the density there is found to be 1.228
kg/m³,a mere 0.27 % difference. The temperature rises
by 0.311 °C and the pressure changes by 0.38 %.
