本文介绍了一种色彩丰富、快速简便的流场图形显示技术,具有八色十五区段的显示能力。以快速响应的组合式总压探头对流场中不同截面作高密度扫描,可以得到用不同颜色显示的等参数(如等压、等温……)流场彩色图形。比较有利于研究流体的三维流动。 本文讨论了这种技术所用设备研制中的主要问题。介绍了近期实验所得结果。讨论了这种技术的特点及其可能的应用范围。 This article presents a rich, fast and easy flow graphical display technology, with eight color fifteen sections of the display capability. High-density scanning of different cross-sections in the flow field with a fast-response combined total pressure probe results in flow field color patterns with different colors such as isobaric, isothermal ...). More conducive to the study of three-dimensional fluid flow. This article discusses the major issues in developing devices for this technology. Introduced the results of recent experiments. Discusses the characteristics of this technology and its possible applications.
