虚拟现实及其在粉尘扩散研究中的应用

Virtual Reality and Its Application in the Study of Dust Dispersion

探讨了国际上流行的虚拟现实技术 ,并针对大气中粉尘扩散的规律 ,以相关数学模型为基础 ,采用 Open GL开发了可精确地调整流场参数和观察视角的粉尘扩散三维动态场景 ,以及在重力、风速等影响因素和射流作用下粉尘扩散的三维场景。该方法为更好地掌握粉尘扩散规律 ,寻求合理预防措施提供了科学依据。

Virtual reality, a new technology in the world, is introduced and discussed according to the regularity of dust dispersion in the atmosphere, and on the basis of mathematical model, a three dimensional dynamic scene of dust dispersion is developed by adopting OpenGL, in which the parameters of flow field and observation view angle could precisely be adjusted. The same 3-D scene under the impact of gravity and wind speed etc, and under the reaction of jet-flow may also be establushed. This method provides scientific criteria for well handling the regularity of dust dispersion, and searching rational preventive measures. This technology also has good appliction prospects in other field of safety science.
