中文摘要 | 本文以分子動力學模擬軟件DL_POLY 來研究兩個奈米級水滴間的碰撞。兩個水滴以不同的相對速度互相正向碰撞,水滴間的勢能模型採用SPC。研究發現:在T=300K 時,碰撞結果在低相對速度範圍內為結合碰撞,在較高相對速度為碎裂碰撞,此結果與前人的研究相符合。然而,在很低相對速度時仍未能觀察到因蒸發粒子的作用所產生的回彈現象。之前的氬液滴正向碰撞研究曾指出,只要相對速度小於某一臨界值時,回彈現象就很容易發生。本研究顯示,在提高溫度至500K 時,此種回彈現象亦可發生在兩個以低相對速度正向碰撞的水滴間。 |
英文摘要 | This paper employs the molecular dynamics simulation package DL_POLY to investigate the head-on collision of two equal-size nanoscale water droplets. Two water droplets of SPC potential model with a different relative speed collide each other. Our studies show that coalescence collisions of two nanoscale water droplets occurs at low relative speed while shattering collisions occurs at a higer relative speed, which are in agreement with the previous results. However, bounce collisions cannot be observed at a lower relative speed. Our previous studies of two nanoscale argon droplets showed that bouncing can easily occur as long as the relative speed is less than a critical value. We will show that bouncing phenomenon can also be discovered in collision of two equal-size water droplets when temperature lifts up to 500K. |
