Buongiorno's nanofluid model is followed to study the bioconvection in two stretchable rotating disks with entropy generation. Similarity transformations are used to handle the problem equations for non-dimensionality. For the simulation of the modeled equations, Homotopy Analysis Method is applied. The biothermal system is explored for all the embedded parameters whose effects are shown through different graphs. There exists interesting results due to the effects of different parameters on different profiles. Radial velocity decreases with increasing stretching and magnetic field parameters. Temperature increases with Brownian motion and thermophoresis parameters. Nanoparticles concentration decreases on increasing Lewis number and thermophoresis parameter while motile gyrotactic microorganisms profile increases with increasing Lewis and Peclet numbers. Convergence of the solution is found and good agreement is obtained when the results are compared with published work.
本文采用布昂吉奥诺的纳米流体模型研究了两个可伸缩旋转盘内的生物对流及其熵产生。相似变换被用于对无量纲问题方程进行处理。同伦分析方法被应用于模拟方程的求解。对所有嵌入参数进行了生物热系统的模拟，通过不同的图形展示了它们的影响。由于不同参数对不同分布的影响，存在着有趣的结果。随着拉伸和磁场参数的增加，径向速度减小。随着布朗运动和热泳参数的增加，温度升高。随着刘易斯数和热泳参数的增加，纳米颗粒浓度减小，而游动旋毛虫微生物的分布随着刘易斯数和佩克莱特数的增加而增加。当将结果与已发表的工作进行比较时，发现了解的收敛性并获得了很好的一致性。
