对气溶胶爆炸抛撒过程中,首次破碎液滴的尺寸分布进行理论和数值研究.基于热力学第二定律的最大熵增理论,建立首次破碎过程满足的方程组约束条件,给出破碎后液滴尺寸分布的确定方法,并对Air-blast喷管实验和Samirant相关实验进行数值模拟预测,与实验数据符合较好.
Theoretical study and numerical simulations are made on size distribution characteristic of initial liquid drops during aerosol explosive dispersal process.With thermodynamic consistent concept,the maximization of entropy generation in the initial breakup process,constraint equations of the problem are derived,and probability distribution function of initial drop size is obtained.Numerical predictions are in agreement with air-blast annular nozzle experimental data and Samirant experimental data.
