Experimental Data on Deformable Bubble Interactions and Acceleration in a Rising Flow

Time-resolved experimental data on bubble pairs rising in a slit channel, obtained via high-speed imaging and automated tracking. The dataset includes bubble centroids, sizes, and velocities for various size ratios and gas flow conditions. It was authored by Xu-Qing Wang and last updated on 2026-05-08.

Use Cases

• Modeling wake-induced entrainment and coalescence based on bubble spacing and velocity data.
• Quantifying the effective hydrodynamic influence range of a leading bubble's wake based on the normalized spacing parameter h/de.
• Predicting the post-acceleration velocity of trailing bubbles using the developed correlation.
• Analyzing bubble acceleration dynamics based on time-resolved centroid and size measurements.

Strengths

• Data is derived from systematic experiments using high-speed imaging combined with automated segmentation and tracking.
• A quantitative correlation is provided to predict the post-acceleration velocity of trailing bubbles.
• The dataset is small (134.9 KB), facilitating quick download and initial inspection.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The experimental scope is limited to bubble pairs in a slit channel, which may not generalize to all flow configurations.
