Laboratory Data on Oxygen Mass Transfer Coefficients Using Floating Soluble Probes

A laboratory study calibrating a floating solid soluble probe for estimating the oxygen mass transfer coefficient (Ka) at the air-water interface. The dataset likely contains experimental results from a stirred tank and a circular hydraulic channel, showing strong correlations between Ka and the dissolution rate of a soluble solid. The work was authored by Murilo de Souza Ferreira and is available via Open Access.

Use Cases

• Calibrating models for oxygen transfer in water bodies based on the described correlation between Ka and VS.
• Studying the influence of Reynolds number on mass transfer based on the reported Ka.VS ratio relationship.
• Developing low-cost techniques for estimating mass transfer coefficients based on the floating solid soluble probe method.

Strengths

• Strong correlation coefficients reported (r = 0.953 for tank experiments, r = 0.895 for channel experiments).
• Experiments were conducted in two distinct apparatuses (jets stirred tank and circular hydraulic channel) under different turbulence levels.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• The description notes that calibrations in natural water bodies and different turbulence structures are still necessary for definitive utility.
• Last update date is unknown; freshness unverified.
