【摘要】 详细介绍了分析法和试验粒子蒙特卡罗法两种计算挡板流导几率的方法,并分别以百叶窗和人字形挡板为例进行计算分析。计算结果表明分析法能正确地给出流导几率变化趋势,但部分结果与现有实验值有差距,而试验粒子蒙特卡罗法得出的结果与实验数据符合较好。更多还原

【Abstract】 The analytical method and Test Particles Monte Carlo method(TPMC) to calculate the transmison probability of the baffle are introduced.The transmission probability of shutter and chevron screens in many different cases are calculated.The results show that the analytical method can predict the transmission probability qualitatively,while the results by TPMC can be in good agreement with the experiment data.更多还原
