✦ Synopsis

An experimental and theoretical investigation

was carried out to study the boiling and spreading of liquid nitrogen and liquid methane on water, in a one-dlmensional configuration.

With the equations of continuity and momentum transfer, a mathematical model was developed to describe the boiling-spreadlng phenomena of cryogens spilled on water.

The model accounts for a decrease in the density of the cryogenic liquid due to bubble formation.

Experimental spreading fronts were successfully slmulated by assuming constant evaporation rates (40 kW/m 2 and 92 kW/m 2 for nitrogen and methane respectively) in the theoretical model.

The mode/ predicts the maximum spreading distance and the time for complete vaporization.
