介绍了用激光多普勒速度测量 (LDA)的方法测定微波萃取器内流体的沉降速度和旋转速度 ,得到沉降速度和旋转速度在内、外环隙不同层数间的分布 ,研究了流量对湍流强度的影响 ;并将测得的数据用Matlab软件编程序画出二维或三维图。同时得出该萃取器应选用较大流量的结论
The method of laser Doppler velocity measurement (LDA) is introduced to measure the sedimentation velocity and the rotation velocity of the fluid in the microwave extractor. The distribution of the sedimentation velocity and the rotation velocity among different layers of the outer annulus is obtained. Turbulence intensity; and the measured data using Matlab software program to draw two-dimensional or three-dimensional map. Concluded that the extractor should choose a larger flow of conclusions
