A compressible viscous two-phase flow of SF_6 and Ar with condensation in a supersonic nozzle is calculated. The flow field is solved with a 3rd-order MUSCL type TVD scheme. The calculation of condensate mass fraction and nucleation rate was based on Becker-Doring's condensation theory. The development of velocity and thermal boundary layer is discussed in detail from the point of view of the interaction between the boundary layer and condensation. Distribution of pressure along the nozzle axis obtained from the numerical calculation is in good accordance with the experimental one in the case of the stagnation pressure region from 20 kPa to 100 kPa. It was found from the result that the condensation takes place in a limited region under relatively high stagnation pressure, which spreads downstream as the stagnation pressure decreases. The temperature and velocity gradients in the boundary layer increase due to the latent heat release of condensation. Consequently, development of the velocity and thermal boundary layers was suppressed by the condensation.
