Transonic two-phase flows around an airfoil in moist air are numerically investigated. The fundamental equations are the compressible Navier-Stokes equations and model equations of the homogeneous nucleation and the droplet growth by the classical condensation theory. The fourth-order compact MUSCL TVD scheme is used to obtain not only the shock but also a weak condensation shock clearly. The speed of sound and the total energy for moist air are estimated by the homogeneous assumption and the thermodynamic relations. Finally, the affects of the condensation shock and non-equilibrium phase change on airfoil performance are discussed.
