THE TEMPERATURE AND TURBULENCE CHARACTERISTICS IN RESS PROCESS

  

Abstract: The inherent characteristics in the rapid expansion process of supercritical fluid solution were analyzed. The temperature change resulted from the throttling expansion of the supercritical fluid, and the strong turbulence in the expansion flow resulted from the quick change of the fluid pressure were experimentally measured. It was proposed that the temperature and turbulence in the expansion flow affect the particle nucleation, growth or coating process significantly.
