Abstract

CSIRO has been experimenting with supersonic flows as a method of rapidly quenching metallic vapors. Cooling rates above one million degrees per second have been achieved. The supersonic flow conditions are achieved through adiabatic expansion of the gas through a Laval nozzle into a vacuum chamber. This paper will describe the basic physics of the process, outlining the CFD modeling of flow in the nozzle, the effects of different flow conditions on the condensation process and discuss the practical design issues associated with operating supersonic nozzles.
