1 · What the graph read from it

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.

2 · The registry

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

This article fully investigates the hydrogen fuel jet mixing behind the strut with a serpentine injector at a supersonic combustion chamber. The main goal of this work is to analyze the three-dimensional flow of hydrogen jet released from the serpentine nozzle by computational technique. The role of serpentine nozzle height is also examined to find the optimum location for fuel mixing. Meanwhile, the extruded serpentine nozzle located behind the strut is also studied. The strength of circulation in these configurations is compared and our results show that the fuel circulation strength is improved when the serpentine nozzle is located in a higher height behind the strut. Moreover, a comparison of the fuel mixing behind the strut indicates this injector has significantly higher fuel mixing efficiency (about 40%) in comparison with a circular nozzle.
