在过去的几年里，有很多关于气体运动的复杂模拟建模工作。在[Fedkiw等人，2001]的工作中，开发了一种新的数值模拟烟雾的方法，该方法结合了Steinhoff和Underhill [Steinhoff和Underhill， 1994]提出的称为“涡度约束”的模型。据我们所知，迄今为止在计算机图形学领域发表的作品中考虑了烟雾粒子的被动平流。在这项工作中，我们将展示粒子质量对烟的运动受底层流场影响程度的影响。我们将借助粒子时间常数τp来说明这些结果。
For the past several years, there has been a lot of work in modelling complex simulations pertaining to motion of gases. In the work of [Fedkiw et al., 2001], a new approach to numerically simulate smoke was developed which incorporates the model proposed by Steinhoff and Underhill [Steinhoff and Underhill, 1994] known as “vorticity confinement”. Passive advection of smoke particles is considered in the works published thus far in the field of computer graphics, to the best of our knowledge. In this work we will show the effect of particle mass which affects the extent to which the motion of smoke is influenced by the underlying flow field. We will show these results with the help of particle time constant (τp).
