直接投入固体粒子示踪物显示气流的研究

Study on displaying air current with solid tracer element

  • 摘要: 根据流体力学相关的理论知识,对采用固体粒子显示气流的跟随特性进行了理论分析,并选用碱式MgCO_3白色粉末作为直接投入物,用实验的方法进行了比较和验证,结果表明:直接投入MgCO_3粉末来显示气流具有良好的可视性和可记录性,可以很直观地观测到流体的流动状况,是一种有效的实验方法.

     

    Abstract: Abstract:Visualizing the fluid object in question can directly observe the fluid flow status. According to the relative theory in fluid dynamics, this paper analyzes the following characteristic of solid tracer element which is used to display air current. With the white powder of MgCO3 as tracer element which is directly put into the air stream, the result of the experiment are compared with that of the theoretical analysis. The results show that it is an effective way to display the air current with powder of MgCO3 as tracer element directly put into the air stream, which has characteristic of good visualization and easy track.
