Thermoacoustic streaming in a linear temperature gradient.
Article in Physical review. E, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Thermoacoustic effects arise when a temperature gradient is present in a sound field. This work investigates the interplay of orthogonal sound and thermal fields in a water-filled microchannel. We measured the three-dimensional streaming in the water-filled cavity for only sound applied, for only thermal gradient, and for the two fields combined. The resulting thermoacoustic streaming was 30 times faster than natural convection and 15 times faster than acoustic streaming. We also performed two-dimensional simulations of the channel's cross section, reaching good qualitative agreement with the measured streaming data. Moreover, we measured the temperature of the fluid both with and without a sound field, showing that the thermal resistance of the channel decreased when the acoustic field was present, while we could not capture this in the current model. We believe our results can have implications for acoustically aided heat exchangers with liquid media.
