Then , a pressure - based height field fluid model is proposed and the pressure to simulate the fluid surface height is justified 在此基础上给出基于压力高度域的水流模型,并阐述了该模型的合理性。
First , a brief summary of the definition phenomena importance and mathematical model of two fluid model is presented 首先对二相流的定义、现象、研究的重要意义及二相流的数学模型进行了简要综述。
The pressure - based height field fluid model can present many important properties of fluid and thus can be used widely 本文讨论的模型能够描述水流的多种属性,这增加了模型的应用范围;同时渲染算法能够满足实时需求。
Based on the two - fluid model , the attenuation process of blast waves in sprays is simulated by using the eulerian - lagrangian method 基于双流体模型,利用euler - lagrange组合方法,对爆炸波在液雾中的衰减过程进行了数值模拟。
By now , numerical simulation of two fluid model is still in its infancy , and our work are on this subject 迄今为止,有关二相流数值模拟过程中双流体模型的研究还不是很成熟,多数工作尚属于探索性的,本文的工作则主要针对这一问题展开。
