Abstract

The simulation of air injection into a liquid (water, liquid lead) at large pressure drops (ΔP = 160 × 105 Pa) has been carried out. A significant difference in the formation of the air volume during injection into water and liquid lead is demonstrated. The shape of the resulting air volume formed during injection into liquid lead is shown to depend on the nozzle diameter. It is established that the presence of interfacial heat transfer at short times does not affect the dynamics of the air jet outflow.
