Simulation Analysis of Flow Field Distribution of Air Purifier Based on CFD

空气净化器在室内运行时的流场测量相对比较困难,相关研究多以计算机仿真手段为主。基于ANSYS CFD软件对室内空气净化器运行时的状态进行仿真分析,该仿真方式可以动态捕捉到空气净化器运行时,其室内适用面积空间内空气流场分布状态、包含空气流动轨迹线,空气流速等数据。仿真结果表明,通过该仿真分析方法可以更加直观的判断空气净化器的实际净化效果,解释说明了空气净化器是如何在密闭空间内完成循环净化的过程,间接的解决了使用者无法感知空气净化器净化效果的问题。

It is relatively difficult to measure the flow field of air purifier when it is running indoors,and the related research is mostly based on computer simulation methods.Based on ANSYS CFD software to simulate and analyze the running state of the indoor air purifier,the simulation method can dynamically capture the air flow field distribution,including air flow trajectory,air velocity and other data in the indoor confined space when the air purifier is running.The simulation results show that the simulation analysis method can more intuitively judge the actual purification effect of the air purifier,explain how the air purifier completes the cycle purification process in the confined space,and indirectly solve the problem that users can not perceive the purification effect of the air purifier.
