基于After Effects的沿江平原河网水流数值模拟可视化探析

Visualization analysis of numerical simulation of river network along the Yangtze River Plain Based on After Effects

通过河网水流数值模拟计算出最佳调度方案,可有效提高河流水体自净能力,达到改善水环境的效果。而如何使水流数值模拟更加直观,让水流"活动"起来,是各级水系调度部门困惑的难题。利用After Effects这样一个制作动态影像的设计软件制作水流模拟动画,可以弥补以往河网水流数值模拟过程中只能采用静态河网图像的缺陷,将After Effects运用到河网数值模拟中,不仅能反映出水流的方向,还能直观地反映水流的速度与流量。本研究就南通市港闸区沿江平原河网水流数值模拟的可视化进行了探讨。

Through the numerical simulation of river network flow,the best scheduling scheme could be calculated,which could effectively improve the self purification capacity of river water and achieve the effect of improving water environment.However,how to make the numerical simulation of water flow more intuitive and make the water flow"activity"is a puzzling problem of the water distribution departments at all levels.Making use of dynamic image design software such as After Effects to make flow simulation animation could make up for the defects which could only be used in the flow numerical simulation of the river network.Meanwhile,applying the After Effect to the numerical simulation of the river network could not only reflect the direction of the water flow,but also directly reflect the speed and flow.The visualization of numerical simulation of river network flow along the river plain in Gangzha District of Nantong City was discussed in the research.
