Heat Transfer Enhancement in a Shell-and-Tube Type of Heat Exchanger Using Al
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Shell-and-tube heat exchangers are widely used in industrial processes, but improving the shell-side heat transfer without causing excessive pressure losses remains a major engineering challenge. Numerical simulations provide an efficient approach for evaluating thermohydraulic enhancement techniques while reducing experimental costs. The present study evaluates the heat transfer in a shell-and-tube heat exchanger using computational fluid dynamics by means of ANSYS Fluent software. Unlike previous numerical studies that mainly focused on thermal enhancement, this work provides a comprehensive thermohydraulic assessment by simultaneously evaluating heat-transfer improvement together with the associated pressure-drop and pumping-power penalties over different nanoparticle concentrations and mass flow rates. Therefore, a simplified heat-exchanger model was developed with six baffles operating under turbulent flow conditions. The working fluid in the shell is initially water, which is subsequently replaced by nanofluid composed of water and 15 nm Al
