摘要

本文介绍了一种先进的模拟多孔弯曲容器内非定常冻结的数值方法,该方法由纳米颗粒和多孔泡沫混合增强。通过综合这些因素并考虑辐射效应,该研究显著加快了冻结过程。用混合纳米流体代替水,凝固时间缩短了6.26%,显示出纳米流体优越的导热性。此外,多孔泡沫的掺入效果非常好,冻结时间缩短了78.77%,而辐射的掺入使冻结时间缩短了25.78%。在基本情况下,仅使用水而不使用多孔泡沫或辐射,冻结时间延长至700.12 s。然而,优化的配置,结合了所有这些技术,将过程缩短到139.30秒,强调了冷储能性能的显着改善。

Effect of a novel hybrid nanomaterial in a porous PCM container on the solidification of water with radiative heat removal

This article introduces an advanced numerical method to simulate the unsteady freezing inside a curved porous container, enhanced with hybrid nanoparticles and porous foam. By integrating these components and accounting for radiation effects, the study significantly accelerates the freezing process. Replacing water with hybrid nanofluids decreases the solidification time by 6.26%, showcasing the superior thermal conductivity of the nanofluid. Additionally, the incorporation of porous foam is highly effective, reducing freezing time by 78.77%, while the inclusion of radiation cuts the time by 25.78%. In a base scenario using only water without porous foam or radiation, the freezing time extends to 700.12 s. However, the optimized configuration, which combines all these techniques, reduces the process to just 139.30 s, underscoring a marked improvement in cold energy storage performance.
