摘要：

为测量与研究仿生功能表面在内流管道中的减阻性能,设计了基于压差测试原理的测试系统。针对内流流动的特点,设计的试验段可拆装并能够安装不同厚度的试样做为流场壁面。设计了基于PLC(可编程序控制器)的数据采集处理与控制系统,并对系统精度进行分析,得出了各流速点对应的均方差极限。利用该系统对弹性表面和弹性导热仿生表面减阻进行了测试与研究,结果表明该系统能够对内流流动中的各种仿生功能表面减阻性能进行测试并具有较高的精度。

Abstract:

To study and measure the drag-reduction performance of bionic functional surfaces with internal flow, a testing system based on differential pressure measurement was designed. Considering the characteristics of the internal flow, the test section is replacable to adapt to the flow field wall with different thickness. The data acquisition, processing and control system was designed based on programmable logic controller. The system precision was analyzed and the mean square errors of different flow velocities were calculated. The elastic silicone rubber and elastic thermal conductive bionic surface was tested using this system. The system can provide a high accuracy analysis and test platform for the study of drag-reduction performance of various bionic functional surfaces with internal flow.

Key words: bionic engineering, bionic functional surface, drag-reduction, elastic thermal conductive, test system
