The purpose of this tutorial is to study the hydrodynamics and bubble formation in a uidized bed over a period of time. It also demonstrates how to customize a drag law for granular gas-solid ow. The default drag law in FLUENT is the Syamla

基于物理的流体模拟近年来成为计算机动画领域的一个研究热点．回顾了该领域中基于物理的流体模拟的发展情况，总结了该研究方向所采用的各类方法，并结合各种现象的特点分门别类地详细展开其方法总体上可 以分为欧拉法和拉格朗日法，涉及的现象包括烟雾、火焰、爆炸、波浪、气泡以及*界面等．最后展望了未来发 展的3个重点：细节策略、加速策略和控制策略，以使整个模拟能够更好地满足人们对真实感、实时性以及灵活性的 需求．-This paper presents a survey on the deve
