Abstract

Stratified thermal storage promotes energy sustainability by storing excess energy during times of low demand for later use making it possible to integrate renewable energy sources like solar and wind. This communication discusses the significance of triple stratification using the Cattaneo-Christov model in the bioconvective flow of thixotropic fluid coexisting with nanoparticles and gyrotactic microorganisms. The Cattaneo-Christov heat and mass flux is incorporated into the fluid model allowing more accurate prediction of heat and mass phenomena in the fluid system. The governing partial differential equations that describe fluid flow are parametrized to yield an ordinary differential equation system by adopting suitable transformations. The series solutions are obtained by applying the homotopy analysis method (HAM). The effects of relevant parameters on the various profiles are revealed and accurately reported. It is observed that amplified thermal stratification lowers the temperature of the fluid. Also, Brownian motion is used to illustrate the random movement of small particles suspended in liquids, and it is envisioned that the concentration distribution is significantly influenced by the Brownian motion of nanoparticles.

探索分层对输送微小颗粒的生物对流触变流体动力学的影响及 Cattaneo-Christov 模型：蓄热系统应用

分层热存储通过在低需求时存储多余能量以供日后使用，使太阳能和风能等可再生能源的整合成为可能，从而促进了能源的可持续性。这篇论文利用卡塔尼奥-克里斯托夫模型讨论了触变性流体与纳米颗粒和陀螺微生物共存的生物对流中三重分层的意义。卡塔尼奥-克里斯托夫热通量和质量通量被纳入流体模型，从而可以更准确地预测流体系统中的热量和质量现象。通过采用适当的变换，将描述流体流动的偏微分方程参数化，从而得到常微分方程系统。通过应用同调分析方法（HAM）获得序列解。揭示并准确报告了相关参数对各种剖面的影响。研究发现，放大的热分层降低了流体的温度。此外，布朗运动被用来说明悬浮在液体中的小颗粒的随机运动，并设想浓度分布受到纳米颗粒布朗运动的显著影响。
