摘要The liquid nitrogen's explosive boiling characteristics under transient high heat flux have attracted increasing attentions of researchers over the world due to its wide applications. Although some experiments have been performed, the process and the characteristics at the initial stage, especially within 1μs, have not been described reasonably yet. Based on the related experiments and theoretical analysis, a novel kinetic model combined with quasi-fluid idea is presented to analyse the characteristics of liquid nitrogen's explosive boiling at the initial stage. The results indicate that the model can appropriately describe the liquid nitrogen's explosive boiling. The behaviour and the heat transfer characteristics of a single bubble are very different from those of the bubble cluster, thus the behaviour of individual bubbles could not be directly applied to describe the explosive boiling process at the initial stage.
