Stochastic Algorithm and Numerical Simulation for Drop Scavenging of Aerosols

  • 摘要: 气溶胶尺度分布的时间演变可量化气溶胶的湿沉降过程,它在数学上可由考虑湿沉降的通用动力学方程来描述.该方程为一典型的部分积分微分方程,与气溶胶尺度分布和雨滴尺度分布均相关,且由于需要考虑Brown扩散、拦截和惯性碰撞等湿沉降机制而使得清除系数模型非常复杂,普通的数值方法难以求解.为此发展了一种新的多重Monte Carlo算法,以求解考虑湿沉降的通用动力学方程,并用于模拟实际环境中气溶胶的湿沉降.对于对数正态分布的气溶胶尺度分布和雨滴尺度分布, 多重Monte Carlo算法进行的数值模拟表明, 雨滴几何平均尺度越小, 雨滴几何标准偏差越小,越有利于小尺度和中等尺度气溶胶的湿去除,而稍微不利于大尺度气溶胶的湿去除.
