“…It is essential that the verification of twophase procedures should be done in prototypical conditions, close to that of AEs as it was discussed above. To this day the following problems were passed: electroconductivity problems: a) simple simulative problem; b) the problem of terminal effect ) natural convection of molten salt with solidification at cooled boundary (Filippov et al 2009) conjugated simulation of effect of rising bubbles on the electrical conductivity (Filippov, Korotkin, Kanaev et al 2008). The verification and identification of the coefficients of the described model of effective body forces is not yet satisfactory performed because of luck of data on bubbles motion in vertical generating channels.…”
