Abstract

The ionic wind, generated by corona discharge from sharp emitters, is extensively used for propulsion and heat/mass transfer enhancement. Accurate speed measurement is critical to optimize the performance of ionic wind generators, especially in systems with multiple emitters where non-uniform flow is prevalent. To address this, a digital balance is used to measure the average speed of the ionic wind using dynamic pressure. The comparison with hot-wire and vane anemometers showed the advantages of dynamic pressure measurement of non-uniform ionic wind speed.

干燥系统中由多发射器放电产生的离子风的动态压力测量

离子风是由尖锐发射器的电晕放电产生的，广泛用于推进和传热传质增强。精确的速度测量对于优化离子风力发电机的性能至关重要，特别是在多发射器的系统中，不均匀流动是普遍存在的。为了解决这个问题，一个数字平衡被用来测量离子风的平均速度使用动态压力。通过与热线式风速计和叶片式风速计的比较，表明了非均匀离子风速动压测量的优越性。

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
