BOILING HEAT TRANSFER COEFFICIENTS OF LIQUID METALS.
A single tube evaporator was designed for investigating heat transter coefficients of liquid metals .t either horizontal or vertical position. The heating element, the evaporating vessel and the :ondenser were made of stainless steel. 
The liquid metals employed were mercury, and amalgams containing various amounts of magne-ium and sodium. The boiling heat transfer coefficients were determined under pressures from 1~11 tmospheres (abs.), heat load from 5000~47000 kcal/m2:hr, and boiling temperatures from 356~ 24℃. 
For mercury, we obtained the following relation,- 
Similar results were obtained for amalgams. Experiments were carried out under N2 atmospheres.
