An incompressible, electrically conducting, bioconvective micropolar fluid flow between two stretchable disks is inspected. Modification versions of Fourier and Fick’s law are accounted through Cattaneo–Christov heat–mass theories. The nanofluid Buongiorno model is also utilized in constitutive equations. The influence of gyrotactic microorganism is also accounted through bioconvection. Similarity variables transform the fluid model into system of ordinary differential equations. The resultant model is then solved through bvp4c method. Results in pictorial and tabular ways are accomplished. It is found that stretching Reynolds number and magnetic parameter slows down the radial velocity at center of the plane. Motile microorganism field is reduced by Peclet number. Micropolar parameters can be useful in the enhancement of couple stresses and in reduction of shear stresses. A comparison is also elaborated with published work under limiting scenario for the validation of numerical scheme accuracy.

检查了两个可拉伸圆盘之间不可压缩的导电生物对流微极性流体流动。傅立叶和菲克定律的修改版通过Cattaneo-Christov热质量理论进行解释。纳米流体Buongiorno模型也用于本构方程。旋回微生物的影响也通过生物对流来解决。相似变量将流体模型转换为常微分方程组。然后通过bvp4c方法求解生成的模型。以图形和表格的方式完成结果。发现拉伸雷诺数和磁参数会减慢平面中心处的径向速度。运动微生物场减少了Peclet数。微极性参数可用于增强耦合应力和减小剪切应力。为了验证数字方案的准确性，还对与在限制方案下发布的工作进行了比较。
