摘要
为了完成内设火灾场景的优化,运用FDS数值模拟软件,对每个场景房间内的温度、能见度及烟气扩散过程进行模拟,以数据、图片、视频的形式输出计算结果。参考数值模拟计算结果,对VR场景进行构建和优化,使得场景中的火灾发展过程更科学真实,进一步增强使用者的体验感和沉浸感。同时,FDS数值计算可以解决大场景火灾缺乏现实数据的问题,为系统的优化升级提供技术支持和数据支撑。
In order to complete the optimization of its built-in fire scenario,FDS is used to analyze the temperature,visibility and smoke diffusion process,and the calculation results are out-put in the form of data,pictures and videos.Then,referring to the numerical simulation results,the VR scene is constructed and optimized to make the fire development process more scien-tific and realistic,and further enhance the user's sense of experi-ence and immersion.At the same time,FDS numerical calcula-tion can solve the problem of lack of real data in large scene fire,and provide technical support and data support for the opti-mization and upgrading of system.
