In this article, we explore how activation energy and varied transit parameters influence the two-dimensional stagnation point motion of nano-biofilm of Sutterby fluids incorporating gyrotactic microbes across a porous straining/shrinking sheet. Prior investigations implied that fluid viscosity as well as thermal conductance are temperature based. This research proposes that fluid viscosity, heat capacity and nanofluid attributes are all modified by solute concentration. According to some empirical research, the viscosity as well as heat conductivity of nanoparticles are highly based on the concentration of nanoparticles instead of only the temperature. The shooting approach with the RK-4 technique is applied to acquire analytical results. We contrast our outcomes with those in the existing research and examine their consistency and reliability. The graphic performance of relevant factors on heat, velocity, density and motile concentration domains are depicted and discussed. The skin friction factor, Nusselt number, Sherwood number and the motile density are determined. As the concentration-dependent properties are updated, the speed, temperature, concentration and motile density profiles are enhanced, but for all concentration-varying factors, other physical quantities deteriorate.
在本文中，我们探讨了活化能和不同的输运参数如何影响含趋旋微生物的萨特比流体纳米生物膜在多孔应变/收缩薄板上的二维驻点运动。先前的研究表明，流体粘度以及热导率是基于温度的。本研究提出，流体粘度、热容量和纳米流体属性均会因溶质浓度而改变。根据一些实证研究，纳米颗粒的粘度以及热导率高度取决于纳米颗粒的浓度，而非仅取决于温度。采用RK - 4技术的打靶法来获取分析结果。我们将我们的结果与现有研究中的结果进行对比，并检验其一致性和可靠性。描绘并讨论了相关因素在热、速度、密度和游动浓度域上的图形表现。确定了表面摩擦系数、努塞尔数、舍伍德数和游动密度。随着浓度相关属性的更新，速度、温度、浓度和游动密度分布得到增强，但对于所有浓度变化因素，其他物理量会变差。
