The gas volume fraction $\\alpha$ and the velocity fluctuations $u'_0$ of the carrier flow before bubble injection are varied, respectively, in the ranges $0\\leq \\alpha \\leq 0.93\\%$ and 2.3 cm/s $\\leq u'_0 \\leq 5.5$ cm/s, resulting in a variation of the bubblance parameter $b$ in the range [0, 1.3] ($b = \\frac{V_r^2 \\alpha}{{u'}_0^2}$, where $V_r$ is the relative rising velocity).
