Considering that many laboratory measurement techniques devoted to fluid mechanics are difficult to implement in field, especially for combustion and explosions, the present authors developed during the last 2 decades, a special type of Mc Caffrey gauges to measure the flow and the turbulence in those harsh situations (Fig. 1). Especially a fully embedded version is now under development and the initial work about this innovation is evoked.

In this paper, the theory underpinning this technique is presented together with some technical details. Limitations are given and comparisons with reference techniques (hot wire in air jets) are presented.

使用改进的 Mc Caffrey 真空计测量恶劣环境中的流量和湍流

考虑到许多实验室流体力学测量技术难以在现场实施,特别是对于燃烧和爆炸,本文作者在过去的 20 年中开发了一种特殊类型的 Mc Caffrey 压力表,用于测量那些恶劣环境中的流动和湍流。情况(图 1)。特别是现在正在开发一个完全嵌入的版本,并引发了有关这项创新的初步工作。

在本文中,将介绍支持该技术的理论以及一些技术细节。给出了限制,并与参考技术(空气喷射中的热线)进行了比较。
