Condensation observed in a three-dimensional large-scale vortex is numerically investigated using a computational code developed by the authors. 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 by assuming a constant radius and the constant number density of nucleus. Three-dimensional flows over single- and double-delta wings in atmospheric flow conditions are calculated and how onset of condensation occurs in the streamwise vortex is parametrically predicted.
