A method is presented for calculating the properties of a stream containing a small fraction of condensed air. By use of this method, it is found that evaporation of condensed phase may change the stream properties appreciably in the compression flow region about models. Pressures measured on the surface of a 10 degree wedge substantiate these findings.
