Entropy generation in bioconvection two-dimensional steady incompressible non-Newtonian Oldroyd-B nanofluid with Cattaneo–Christov heat and mass flux theory is investigated. The Darcy–Forchheimer law is used to study heat and mass transfer flow and microorganisms motion in porous media. Using appropriate similarity variables, the partial differential equations are transformed into ordinary differential equations which are then solved by homotopy analysis method. For an insight into the problem, the effects of various parameters on different profiles are shown in different graphs.

Cattaneo–Christov热对流动力学和生物对流Oldroyd-B纳米流体的质量通量理论

利用Cattaneo-Christov热和质量通量理论研究了生物对流二维稳态不可压缩非牛顿Oldroyd-B纳米流体中的熵产生。达西-福希海默定律用于研究热和传质流以及多孔介质中微生物的运动。使用适当的相似性变量，将偏微分方程转换为常微分方程，然后用同伦分析方法求解。为了深入了解该问题，在不同的图中显示了各种参数对不同配置文件的影响。
