Dynamic Analysis of Two Rotating-Particles Collision Process by Molecular Dynamics Method

Introduction Whether the rotational motion of a particle involved in a collision process should be taken into account in a mathematical model is a matter of interested concerned. Dynamic analysis has been done without considering such the rotational motion [1], [2]. The purpose of this study is to take a basic knowledge of how much the rotational motion affects the size of a coalesced particle. A computer code is developed to examine the dynamics of two rotating-particles collision process. When the collision between the two particles takes place, it will lead to a coalesced process. The size distribution of coalesced particle is revealed from a microscopic point of view. Computer simulation suggested that the effect of the rotational motion is noticeable in the early stage of the particle growth process.
