【英文篇名】 Numerical analysis of biological particles movement in two adjacent rooms 【作者中文名】 赵彬; 张颖; 李先庭; 【作者英文名】 By Zhao Bin ★; Zhang Ying and Li Xianting ★Tsinghua University; Beijing; China; 【作者单位】 清华大学; 【文献出处】 暖通空调, Hv SARS; 通风; 数值模拟; 【英文关键词】 particle; SARS; ventilation; numerical simulation; 【摘要】 采用数值计算方法对穿堂风条件下 ,外区房间中性质和SARS病毒类似的生物颗粒的运动情况及其对相邻的内区房间的影响进行分析。对不同的换气次数、不同的室内颗粒初始位置等工况进行了数值分析。结果表明 ,外区房间自然通风换气量的加大 ,可能会导致内区房间的生物颗粒数量增多 ;而颗粒初始位置距离内、外区相邻开口越近 ,运动到内区房间的颗粒数量也越多。 【英文摘要】 Numerically studies the movement of biological particle which has similar property as SARS virus particle in two adjacent rooms under the cross ventilation. Compares the cases of different air exchange rate and initial positions of particles. The result shows that the number of biological particles in an inner zone room increases with the increase of the air exchange rate of the adjacent peripheral zone room. And if the closer the particles are to the conjoint opening of the two rooms, the more the particle...
