Identification of two phase flow regimes by void fraction measurements

Abstract: Abstract. This paper will present a method to identify flow patterns (bubble & slug flow) in vertical air-water two-phase flow by void fraction measurement (using an impedance probe) at Inst. of Mechanics Hanoi.

“…The analysis of a RC model shows a simple way to associate the overall two-phase mixture behavior with their corresponding arranged electrical elements. The parallel arrangement seems to have been frequently assumed without experimental verification (dos Reis and da Silva, 2014;Micaelli, 1982;Bernier, 1982;Tournaire, 1986, 1987, Sainz-Jabardo and Bouré, 1988Kytömaa and Brennen, 1988;Jaworek et al, 2004;Tri, 2005;Wu et al, 2015), series arrangement 544 www.rmiq.org does not seem to have been reported. This kind of models is used for the evaluation of the behavior of the electrical impedance sensor in the frequency domain, to determine the operation mode, i.e.…”

“…Sin embargo, Tri (2005) propone que su sistema de electrodos se comporta como un transductor capacitivo, donde la impedancia tiene una conexión de componentes en serie, esto difiere del modelo empírico ya reportado del sistema aire-agua. La conclusión que podemos observar con respecto a la impedancia, es que el término de la reactancia toma una forma capacitiva: X C = 1/(2πf C), donde f es la frecuencia del voltage alterno y C es la capacitancia del líquido.…”
