The objective of this study is to provide experimental data applied to the validation of detailed two-phase flow simulation codes. To achieve this aim, we propose the developed measurement method for gas-liquid two-phase bubbly flow through the combination of Laser Doppler Velocimetry (LDV) and photodiode technology. This method is capable of simultaneously measuring liquid velocity and local void fraction. The development plan is briefly introduced in the presentation.
