“…It can also be noted that for cases corresponding to wall-peak void distribution, mean chord length values presents a peak near the wall. This phenomena is well explained by (Kalkach-Navarro et al, 1993) from the fact that the presence of a wall limits the arc length at which the bubble is intercepted, thus the radial location of the peak is related to maximum bubble radius.…”

“…The existing literature for needle probe sensors (Kataoka et al, 1986;Kataoka and Serizawa, 1990;Revankar and Ishii, 1992;Kalkach-Navarro et al, 1993;Cartellier, 1999;Dias et al, 2000;Fu, 2001;Wu et al, 2001;Kim et al, 2001;Euh et al, 2001;Shen et al, 2005;Pradhan et al, 2013) is employed to measure the local two-phase flow parameters in the present work. The four-sensor conductivity probe design used in the present experiments is based in the previous work of (Kim et al, 2001) and consisted of 4 enamelled copper wires (0.2 mm outer diameter).…”

“…Kalkach, Lahey, Drew and Meyder (Kalkach, 1993) have extended Kataoka's experimental work with an improved multi-point probe and reported data at a variety of different phase fractions and velocities for gas-liquid flow. However, they did not attempt to correlate the data.…”

“…Wu y colaboradores [Wu1999] propusieron un factor de corrección para la sonda de dos puntas mediante la comparación de medidas experimentales y simulaciones numéricas detalladas, en cuanto a la calibración teórica del sensor han sido realizados por el profesor Muñoz-Cobo y sus colaboradores [Muñoz-Cobo2007]. Kalkach-Navarro [KalkachNavarro1993] efectuaron mediciones locales empleando sondas de dos puntas con un modelo teórico derivado de la suposición de que las burbujas son esféricas cuyo tamaño puede representarse por una función distribución de probabilidad Por otra parte, la sonda de cuatro puntas permite medir las tres componentes de la velocidad superficial cuando la burbuja pasa a través de los cuatro sensores [Kataoka1986]. En años recientes se han realizado pruebas experimentales en las que sondas de cuatro puntas han sido empleadas en flujos bubbly, bubbly finamente disperso, en regimenes en transición, en flujos bala y en flujo anular [Kim2000] [Shen2005] [Jeong2008] [Hazuku2007]; y en configuraciones de mas de cuatro sensores [Euh2001].…”
