Mass Transfer Simulation Model for Justification Sodium Purification System Characteristics

Numerical simulation of a sodium cold traps performance characteristics is discussed within this paper. The method of consecutive heat and mass transfer simulation using custom open source CFD solver to determine the mass transfer and retain coefficients for the cold trap mock-up is discussed in this work. The new solver has been developed, which calculates fields of dissolved oxygen and suspended sodium oxide particles and the rate of their accumulation in the cold trap as well. It has been demonstrated that suggested methodology of CFD simulation allows one to analyze operational parameters of a sodium purification systems for nuclear facilities. (author)
