I wonder if this could be a nontrivial, alternate explanation for the erosion of materials in turbulent flows (ship propellers are a great example).
If so, it could change the way people design and manufacture these components.
There would be implications in the maritime and hydrocarbon industries, as well as in hydro power.
- not_a_cop75 7y agoExplains well the title of "Universal Solvent" if so.
- hinkley 7y agoIt’s been a long time since this has made headlines. Last time it was microcavitation. Has that been debunked?
- mogadsheu 7y agoGreat point. What I’m suggesting is that, based on the article, perhaps there’s an alternate or (more likely) supplemental explanation to microcavitation. Maybe the baby bubbles bursting apply both exert a physical and a chemical (per the article’s discovery) effect on the substrate. If nontrivial, applying/developing different coatings that are more resistant to h2o2 could be useful in real world applications. I really don’t know, but it’d be a logical next step for applied research!
- patrec 7y agoWouldn't someone have noticed the chemical corrosion – even if not specifically looking for it?

- deelowe 7y agoIsn't cavitation a pretty well understood phenomenon? If something else was going on, wouldn't the models be incorrect?
- mogadsheu 7y agoHonestly I wouldn’t know, just musing! My background definitely isn’t in fluid flow. A quick search suggests that cavitation modeling is actively being updated (src: https://aip.scitation.org/doi/10.1063/1.5052257 https://aip.scitation.org/doi/10.1063/1.5052257), but I don’t know to what degree they’re refining them. Not my area of focus.
