Transonic viscous flows around a wing in atmospheric conditions are numerically investigated. Fundamental equations contain conservation laws of mixed gas, water vapor, water liquid, and the number density of nucleus, momentum equations, and the energy equation. Classical condensation theory is used for modeling homogeneous nucleation and nonequilibrium condensation. Heterogeneous nucleation is approximately modeled assuming a constant radius and the constant number density of nucleus. These equations are solved by the fourth-order accurate compact MUSCL TVD scheme and LU-SGS scheme. The effect of condensation to transonic flows around a wing is evaluated by changing atmospheric conditions.
