The main object of the present paper is to examine and compare the improvement of flow and heat transfer characteristics between a rotating nanofluid and a newly discovered hybrid nanofluid in the presence of velocity slip and thermal slip. The influence of thermal radiation is also included in the present study. The system after applying the similarity transformations is solved numerically by using the bvp-4c scheme. Additionally, numerical calculations for the coefficient of skin friction and local Nusselt number are introduced and perused for germane parameters. The comparison between water, nanofluid and hybrid nanofluid on velocity and temperature is also visualized. It is observed that the velocity and temperature distributions are decreasing functions of the slip parameter. Temperature is boosted by thermal radiation and rotation. It is found that the heat transfer rate of the hybrid nanofluid is higher as compared to the traditional nanofluid.
本文的主要目的是研究和比较旋转纳米流体与新发现的混合纳米流体在存在速度滑移和热滑移情况下的流动和传热特性的改善情况。本研究还考虑了热辐射的影响。应用相似变换后的系统通过使用bvp - 4c格式进行数值求解。此外，引入并研究了表面摩擦系数和局部努塞尔数的数值计算，以分析相关参数。还可视化了水、纳米流体和混合纳米流体在速度和温度方面的比较。观察到速度和温度分布是滑移参数的递减函数。热辐射和旋转会提高温度。结果发现，与传统纳米流体相比，混合纳米流体的传热速率更高。
