Argon Nucleation in a Supersonic Nozzle,
Abstract
Experiments on the condensation of gaseous argon by homogeneous nucleation have been carried out in a supersonic nozzle at pressures high enough so that the phase change occurs under collision dominated or continuum flow conditions. In addition, the argon is precooled in a liquid nitrogen heat exchanger so that the onset of nucleation takes place at a low enough Mach number (1.85 in this case) such that the experiments can be interpreted through the use of one-dimensional gasdynamics. The supply pressure and temperature are varied so that the onset of condensation occurs at the nozzle exit, as detected through the use of laser light scattering.
