Due to enhanced heat transfer rate, the nanofluid and hybrid nanofluids have significant industrial uses. The principal objective of this exploration is to investigate how thermal radiation influences the velocity and temperature profile. A water-based rotational nanofluid flow with constant angular speed [Formula: see text] is considered for this comparative study. A similarity conversion is applied to change the appearing equations into ODEs. Three different nanoparticles i.e., copper, aluminum, and titanium oxide are used to prepare different nanofluids for comparison. The numerical and graphical outputs are gained by employing the bvp-4c procedure in MATLAB. The results for different constraints are represented through graphs and tables. Higher heat transmission rate and minimized skin friction are noted for triple nanoparticle nanofluid. Skin coefficients in the x-direction and y-direction have reduced by 50% in trihybrid nanofluid by keeping mixed convection levels between the range [Formula: see text]. The heat transmission coefficient with raising the levels of thermal radiation between [Formula: see text] and Prandlt number [Formula: see text] has shown a 60% increase.
由于传热速率的提高，纳米流体和混合纳米流体具有重要的工业用途。本研究的主要目的是研究热辐射如何影响速度和温度分布。本对比研究考虑了具有恒定角速度[公式：见原文]的水基旋转纳米流体流动。应用相似变换将出现的方程转化为常微分方程。使用三种不同的纳米颗粒，即铜、铝和氧化钛来制备不同的纳米流体进行比较。通过在MATLAB中采用bvp - 4c程序获得数值和图形输出。不同约束条件下的结果通过图表表示。对于三纳米颗粒纳米流体，注意到具有更高的传热速率和最小化的表面摩擦。通过将混合对流水平保持在[公式：见原文]范围内，三混合纳米流体在x方向和y方向的表面系数降低了50%。在热辐射水平在[公式：见原文]和普朗特数[公式：见原文]之间升高时，传热系数显示增加了60%。
