摘要

多相流在工业和自然界中有各种应用。多相流最重要的子类别之一是气液流，主要存在于蒸发器、冷凝器、微型反应器、低温发动机和紧凑型热交换器中。在本研究中，使用红外收发器和耳机插孔对内径4.7mm、厚度0.3mm的玻璃管中的空气-水两相流进行了表征。红外接收器的输出使用3.5毫米耳机插孔发送到笔记本电脑。本工作的新颖之处在于，这消除了对专用微控制器/DAQ系统处理数据的需要。用python编写的一个简单程序用于处理麦克风的输入，并提供识别流态的振幅和频率信息。同时捕获的高速图像用于验证使用耳机插孔获得的输出。

Intelligent Flow Regime Identification Using IR Sensor and 3.5mm Headphone Jack

Multiphase flow occurs in variety of applications in Industries and in nature. One of the most important subcategory of multiphase flow is gas-liquid flows predominantly found in evaporators, condensers, micro-reactors, cryogenic engines and in compact heat exchangers. In the present study, air-water two phase flows in a 4.7mm inner diameter glass tube with 0.3mm thickness is characterized using an IR transceiver and a headphone jack. The output of the IR receiver is sent to the laptop using a 3.5mm headphone jack. The novelty in the present work is that this eliminates the need for a dedicated micro-controller/ DAQ system to process the data. A simple program written in python is used to process the input of the mic and provide amplitude and frequency information which identifies the flow regime. High-Speed Images captured simultaneously are used to validate the output obtained using the headphone jack.

期刊介绍： International Journal of Automation and Smart Technology (AUSMT) is a peer-reviewed, open-access journal devoted to publishing research papers in the fields of automation and smart technology. Currently, the journal is abstracted in Scopus, INSPEC and DOAJ (Directory of Open Access Journals). The research areas of the journal include but are not limited to the fields of mechatronics, automation, ambient Intelligence, sensor networks, human-computer interfaces, and robotics. These technologies should be developed with the major purpose to increase the quality of life as well as to work towards environmental, economic and social sustainability for future generations. AUSMT endeavors to provide a worldwide forum for the dynamic exchange of ideas and findings from research of different disciplines from around the world. Also, AUSMT actively seeks to encourage interaction and cooperation between academia and industry along the fields of automation and smart technology. For the aforementioned purposes, AUSMT maps out 5 areas of interests. Each of them represents a pillar for better future life: - Intelligent Automation Technology. - Ambient Intelligence, Context Awareness, and Sensor Networks. - Human-Computer Interface. - Optomechatronic Modules and Systems. - Robotics, Intelligent Devices and Systems.
