← ScienceWhich outcome occurs when supersonic airflow cools below the dew point and contains condensation nuclei?
A)Prandtl-Meyer expansion wave condensation
B)Wilson cloud formation✓
C)Rayleigh scattering enhancement
D)Boundary layer separation suppression
💡 Explanation
Supersonic cooling to saturation induces spontaneous condensation; the Wilson cloud forms due to adiabatic expansion. Latent heat transforms the moist air from vapor to liquid, because the air is supersaturated, therefore, phase changes, rather than other effects dominate.
