Abstract

Developments in space and in nuclear energy have demonstrated the heat transfer utility of liquid metals in both low pressure and high temperature applications. Compared with water or organic liquids, liquid metals are advantageous in the design of thermal features, as for heat transport at high temperatures at normal pressures. Nowadays, sodium is used in the fast breeder reactors, because of its low neutron absorption. Furthermore, liquid metals have also been used in cooling valves, in heat pipes, and for driving Stirling engines. In fast reactors, boiling represents a disturbing occurrence which must be avoided, or controlled as much as possible. The main factors determining the course of the disturbance are the inception superheat, the flow patterns and the boiling characteristics. These factors are connected in a rather complex way. This paper deals with basic research in the liquid metals boiling field, including the inherent tendency of liquid metals to superheat before the initial boiling point, the flow pattern during boiling, and the two-phase flow boiling characteristics.
