基于流体动力学在VR中的研究

Research on Fluid Dynamics in Virtual Reality

在高层建筑的设计中,经常会计算高层建筑的风载荷是否合格,并附上相应的数据或者图片给予论证,但这些数据和图片只有在相关领域内拥有这些知识的专家才能明白其中的含义。而在计算机技术和硬件高度发达的今天,可以通过数值数学和计算机科学结合将复杂的数据和单一的图片转变成三维动态图形并使用Unreal Engine强大的实时渲染功能,以VR的形式高度自由地观看三维动态图形在建筑内外部的运行轨迹和方向,将在设计前期存在的问题得以及时更正。并且这项可视化技术凭借节约成本、提高效率、缩短设计周期等等优势,不仅可以应用在建筑业本身,在汽车仿真、航空航天、轨道交通等等领域内也可应用。

In the design of high-rise buildings, it is often necessary to calculate whether the wind load of high-rise buildings is qualified or not, and to attach corresponding data or pictures to prove them. But these data and pictures can only be understood by experts who have these knowledge in relevant fields. Today, with the highly developed computer technology and hardware, it is possible to combine numerical mathematics and computer science to make them complex. Converting data and a single picture into three-dimensional dynamic graphics and using the powerful real-time rendering function of Unreal Engine, and viewing the trajectory and direction of three-dimensional dynamic graphics inside and outside the building freely in the form of VR, the problems in the early stage of design can be corrected in time. Moreover, this visualization technology relies on the advantages of saving costs, improving efficiency and shortening the design cycle, etc. It can be applied not only in the construction industry itself, but also in the fields of automobile simulation, aerospace, rail transit and so on.
