Abstract
  • A cold trap is a device used to remove certain impurities from a liquid metal by controlled precipitation of such impurities. An investigation of the thermal characteristics of laminar flow in two air-cooled cold traps was made. This investigation showed that the sodium heat transfer rate is a function of the Peclet number. Generally accepted methods of calculating heat transfer to air produce satisfactory results when used to predict cold trap heat rejection rates. A computer code for mathematical simulation of cold trap performance was written and tested. Simulation of cold trap operation was excellent, but prediction of economizer performance was disappointing. The bases f o r constant trapping temperature and constant impurity removal trapping rates were developed. The constant impurity removal trapping rate, a linear function, is used most often in cold trap operation.
