Preliminary experimental results of nucleation of water vapor in methane at high pressure are presented. The results are obtained by applying the nucleation pulse method, using a modified shock tube. The nucleation conditions were taken at two different temperatures (250 K and 240 K) and three different pressures (10 bar, 25 bar and 40 bar).

    At elevated temperatures, droplet growth becomes very fast. We present a new method to generate a nucleation pulse using a shock tube. This method is particularly suitable for nucleation and growth studies at high-temperature conditions, because the falling edge of the nucleation pulse is very...
