摘要
目前监控系统中管道内流体流动的仿真主要采用斑马动画,但该方法不能表达湍流、密度等流体属性。本文在分析了管道内流体物理模型、层流和湍流两种流体运动状态的基础上,提出了以流体质点为核心的仿真办法,流体质点具有受压力而流动、湍流时摄动等属性,来表达流体运动的特点。仿真结果表明该方法比斑马动画更逼真地描绘了管道内流体运动,可有效地增强监控系统界面的动态流程效果。
Animated zebra arithmetic is often used in monitored system to simulate liquid movement in pipes, but this method cannot represent liquid onflow and density properties etc. In this paper a new simulate method that takes liquid particle as kernel is presented based on analysis of liquid physical model and two type of movement status in detail. Liquid particles impersonate liquid movement characteristic, particles have some important properties such as movement by pressure and random movement when liquid is onflow. Simulation results indicate that this method is more realistic than animated zebra arithmetic to portray liquid movement , can enhance interface dynamic effect of monitored system effectively.
