Counter-Current Gas-Liquid Film Cross-Flow for the Staggered Tube Bundles in Closed Wet Cooling Towers

Chemical Engineering Transactions, 2018
This work establishes a three-dimensional CFD model that is capable of describing the counter-current air-water flow across a staggered tube bundle in a bench-scale wet cooling tower (CWCT) by combining the VOF multiphase method and the SST k-ω ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

interThermalPhaseChangeFoam—A framework for two-phase flow simulations with thermally driven phase change

SoftwareX, 2016
The volume-of-fluid (VOF) approach is a mature technique for simulating two-phase flows. However, VOF simulation of phase-change heat transfer is still in its infancy.

Mechanistically Interpretable Artificial Intelligence for Designing Oxygen Electrocatalysts

Advanced Materials, EarlyView.
Mechanistically interpretable artificial intelligence screens nearly seven million perovskite compositions and identifies key descriptors—d‐p hybridization and densification resistance—that govern oxygen electrocatalysis. The discovered BaCo0.8Nb0.1Zr0.1O3‐δ achieves a record 2.68 W cm−2 peak power density at 600°C with over 500 h of durable operation ...
