Summary: The application of machine learning, specifically neural networks (NNs) and genetic algorithm (GA), is studied for multi-objective optimization of heat exchangers. Taking the tube fin heat exchanger (TFHE) as the research object, the study optimizes the inlet air velocity and tube ellipticity. Computational Fluid Dynamics (CFD) simulation is used to obtain optimal heat transfer performance and pressure drop performance for different Reynolds and tube ellipticity values. The simulation data is then used to train Back-Propagation neural networks and establish prediction models for heat transfer coefficient and pressure drop. The non-dominated multi-objective genetic algorithm (NSGA-II) is employed to optimize the NNs' prediction results. The optimization results show significant improvements in pressure drop and heat transfer coefficient for specific Reynolds and ellipticity values.

Summary: This paper investigates how to improve the performance of dielectric materials in capacitors. It chooses the ferroelectric polymer poly(vinylidene fluoride) (PVDF) as the matrix and uses linear polymers polyimide, cyanoethyl pullulan (CR-S), polyethersulfone, and cyanoethylated cellulose as fillers to prepare an all-organic dielectric composite film. The experimental results show that the composite film exhibits excellent electrical properties when the CR-S doping content is 5 wt. %. The all-organic dielectric composite based on CR-S/PVDF offers a significant improvement compared with other dielectric composites.

Summary: The research thoroughly investigated the adsorption mechanism of three chemically-diverse micropollutants on CPN, showing that both anionic and cationic exchange sites coexist on the CPN and can adsorb simultaneously without compromising each other. The adsorption of non-ionic micropollutants was enhanced in the presence of charged micropollutants due to a synergistic effect. The study also demonstrated the efficient filtration of effluent organic matter and micropollutants from TWW by CPN columns compared to granular activated carbon columns.

Summary: In this study, particle resolved calculations were used to investigate the laminar, incompressible, unsteady oscillatory flow and convective heat transfer of nanofluid around a porous cuboid. The effects of various factors such as Reynolds number, volume fraction of nanoparticles, aspect ratio of the cuboid, Darcy number and inlet velocity profile were examined. The results demonstrated that increasing Reynolds number enhanced thermal performance, increasing volume fraction of nanoparticles increased Nusselt number but also led to a stronger increase in pressure drop coefficient, and increasing aspect ratio of the cuboid improved both heat transfer and pressure drop coefficient. The optimal frequency for heat transfer and pressure drop was found to be 9.
