Résumé

The conditions for the formation of ice particles were investigated theoretically by the diffusion-controlled evaporation model. The model was proved to agree with experiments. Finally, based on the results, the vacuum chamber was designed, and spherical ice particles of size below 300 micrometers were experimentally obtained by spraying water droplets of ambient temperature in the vacuum chamber. It was found that the spray flow rate influences the performance of the system more than the position of spray nozzle.
