Abstract:
Based on the experimental work, thermal hydraulic characteristics of sodium boiling are theoretically researched. The object of calculation is an annulus. Liquid sodium is considered incompressible while sodium vapor is considered compressible. Homogeneous flow model is used in the two phase region and upwind scheme integral is used during the calculation. The calculated results showed good agreement with the experimental data, moreover, this work shows good predictive ability as expansion of the experiments.
