Abstract

Two-phase flow is a common occurrence in various industries. Void fraction measurement is a crucial parameter in any two-phase flow because it gives the qualitative and quantitative information about the material in flow channel. This measurement is also important for scheduling maintenance and operation monitoring. In the present research work a novel noninvasive interdigital electrode based capacitive sensor for measurement of void fraction/phase fraction in two phase flow with multiple dimensions and multiple signal conditioning circuits are presented. These sensors are simulated using FEA method and experimentally evaluated on a custom designed experimental setup. The output characteristics of the sensors are analyzed and the capacitance change is in pF range for the whole range of void Fraction i.e. 0 %–100 %.

空隙率测量数字式电容式传感器的设计与研制

两相流在各个行业中都很常见。在任何两相流中，空隙率的测量都是一个至关重要的参数，因为它可以提供流道中物质的定性和定量信息。这种度量对于安排维护和操作监视也很重要。本文提出了一种基于数字间电极的无创电容式传感器，用于测量具有多维度和多重信号调理电路的两相流中空隙率/相率。这些传感器采用有限元方法进行了仿真，并在定制的实验装置上进行了实验评估。分析了传感器的输出特性，在空隙率为0% ~ 100%的整个范围内，电容变化在pF范围内。

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.
