摘　　要：The heat transfer between two corresponding plates,disks,and concentric pipes has many applications,including water cleansing and lubrication.Furthermore,TiO_(2)-water-based nanofluids are used widely because it is useful for operating and controlling the temperature,especially in photovoltaic technology and solar panels.Motivated by these applications,the current study is based on the nanoparticle aggregation effect on magnetohydrodynamics(MHD)flow via rotating parallel plates with the chemical reaction.To achieve maximum heat transportation,the Bruggeman model is used to adapt the Maxwell model.Also,melting and thermal radiation effects are considered in the modeling to discuss heat transport.The Runge-Kutta-Fehlberg 4th−5th order method is used to attain numerical solutions.The main focus of this study is to see the thermodynamic behavior considering several aspects of nanoparticle aggregation.The heat transfer rate between the parallel plates is enhanced by improving the thermophoresis,radiation,and Brownian motion parameters.The rise in Schmidt number and chemical reaction rate parameter decreases the concentration distribution.This study will be helpful in enhancing the thermal efficiency of photovoltaic technology in solar plates,water purifying,thermal management of electronic devices,designing effective cooling systems,and other sustainable technologies.两个相应的板、盘和同心管之间的传热有许多应用,包括水清洗和润滑。此外,TiO_(2)水基纳米流体在操作和控制温度方面具有重要作用,特别是在光伏技术和太阳能电池板中。受这些应用的启发,目前的研究是基于纳米颗粒聚集效应对磁流体动力学(MHD)流动的影响,通过旋转平行板进行化学反应。为了实现最大的热传输,使用Bruggeman模型对Maxwell模型进行修正。此外,在建模中考虑了熔化和热辐射效应热传输。采用Runge-Kutta-Fehlberg4-5阶方法求解。本研究重点是观察考虑纳米粒子聚集的几个方面的热力学行为。通过改进热泳、辐射和布朗运动参数,提高了平行板之间的传热速率。施密特数和化学反应速率参数的增大降低了浓度分布。本研究将有助于提高太阳能板光伏技术的热效率、水净化、电子设备的热管理、设计有效的冷却系统和其他可持续技术。
