2026-08-19 Experimental Investigation of Bubble Dynamics in gas-LBE Two-Phase Flow Across Diverse Pipe Geometries doi:10.57760/sciencedb.j00186.01228 en This dataset originates from an experimental study on gas‑liquid two‑phase flow in molten Lead‑Bismuth Eutectic (LBE), conducted to investigate bubble behavior. The experiments were performed in circular pipes with various inner diameters. We acquired detailed radial and axial profiles of void fraction, bubble velocity, interfacial area concentration, chord length, and bubble frequency. The data reveal a core‑peaked void fraction distribution, and lognormal chord‑length distributions. Additionally, we provide differential pressure signals (both mean values and fluctuation amplitudes) along with their frequency‑domain characteristics, including Power Spectral Density (PSD), spectral entropy, and low‑frequency energy ratio. two-phase flow; electrical probe; LBE Hong Zhang Longxiang Zhu RESTRICTED dataset Science Data Bank
