The study of how energy undergoes changes in physio-chemical interactions involving AlO and γ-AlO with water and CHO within converging and diverging channels is of great significance, given its potential applications in today's advanced technology. We have used two types of oxide nanoparticles, namely, AlO and γ- AlO, with water and CHO. The purpose of this study is to investigate an innovative comparative magnetohydrodynamic (MHD) nanofluid flow and heat transport with the impact of thermal radiation on water and ethylene glycol (EG) suspended with AlO and γ-AlO nanoparticles. A novel comparison of concentration of AlO-H2O, γ-AlO-HO, and γ AlO-CHO nanofluids is investigated under the influence of chemical reactions. The system of nonlinear ordinary differential equations was obtained via a similarity transformation and then solved using the homotopy analysis method (HAM) in Mathematica. The temperature and velocity profiles are obtained numerically for a range of controlling parameter values, including the volume percentage of nanomaterials, the magnetic effect parameter M, the radiation parameter Rd, and Eckert number Ec in convergent/divergent channels. The concentration profiles of AlO-HO, γ-AlO-HO, and γ-AlO-CHO tri-nanofluids are calculated numerically for governing parameter values, including those accounting for chemical reactions. The investigation's findings indicate that there is greater heat transport in γ-AlO-CHO and γ-AlO-HO than in AlO-HO. We have demonstrated that there is good agreement between the current results and those found in the literature for various values of the magnetic field parameter, thermal radiation parameter, and nanoparticle volume fraction.
研究能量在涉及氧化铝（AlO）和γ - 氧化铝（γ - AlO）与水以及碳水化合物（CHO）在收敛和发散通道中的物理化学相互作用中如何变化具有重要意义，鉴于其在当今先进技术中的潜在应用。我们使用了两种类型的氧化物纳米颗粒，即氧化铝（AlO）和γ - 氧化铝（γ - AlO），以及水和碳水化合物（CHO）。本研究的目的是研究一种创新的比较磁流体动力学（MHD）纳米流体流动和热传输，以及热辐射对悬浮有氧化铝（AlO）和γ - 氧化铝（γ - AlO）纳米颗粒的水和乙二醇（EG）的影响。在化学反应的影响下，对氧化铝 - 水（AlO - H₂O）、γ - 氧化铝 - 水（γ - AlO - H₂O）和γ - 氧化铝 - 碳水化合物（γ - AlO - CHO）纳米流体的浓度进行了新颖的比较研究。通过相似变换获得非线性常微分方程组，然后在Mathematica中使用同伦分析方法（HAM）求解。对于一系列控制参数值，包括纳米材料的体积百分比、磁效应参数M、辐射参数Rd和埃克特数Ec，在收敛/发散通道中数值获得温度和速度分布。对于包括考虑化学反应的控制参数值，数值计算氧化铝 - 水（AlO - H₂O）、γ - 氧化铝 - 水（γ - AlO - H₂O）和γ - 氧化铝 - 碳水化合物（γ - AlO - CHO）三纳米流体的浓度分布。研究结果表明，γ - 氧化铝 - 碳水化合物（γ - AlO - CHO）和γ - 氧化铝 - 水（γ - AlO - H₂O）中的热传输比氧化铝 - 水（AlO - H₂O）中的更大。我们已经证明，对于磁场参数、热辐射参数和纳米颗粒体积分数的各种值，当前结果与文献中发现的结果之间存在良好的一致性。
