摘要

微生物在许多情况下发挥重要作用,如毒素释放,消化和抗生素。活动生物的这些显著特征可以导致生物对流现象。鉴于此,本文的重点是研究运动生物和纳米颗粒对流动通过弹性多孔表面的集体影响。为了获得物理上真实的分析结果,还施加了热辐射、粘性耗散和规定的表面滑移条件。流动控制问题采用动量和能量的基本定律进行建模,然后利用适当的标度分析对其进行转换。新出现的各种参数对物理兴趣量的作用以图形方式描绘并以物理方式讨论。观察到,随着辐射参数的增加,流体的速度和温度升高,而流体的浓度下降。局部运动密度随耗散、吸力和辐射因子的增大而增大,随滑移因子的增大而减小。随着注射液体的增加,皮肤摩擦系数、努塞尔数、舍伍德数和活动微生物密度也随之增加。

Radiative slip transport of magnetized gyrotactic micro-organisms submerged with nano fluid along a vertical stretching surface with suction/injection effects
Micro-organisms play an important role in numerous conditions such as toxin release, digestion and antibiotics. These remarkable features of motile organisms can lead to bio convection phenomena. Keeping in view, the present article is focused to study the collective impact of motile organisms and nanoparticles on flow past an elastic porous surface. Thermal radiation, viscous dissipation and prescribed surface slip condition is also imposed in order to acquire physically realistic analysis. The flow governing problem is modeled using fundamental laws of momentum and energy which afterward is transformed by utilizing a suitable scaling analysis. Role of emerging sundry parameters on quantities of physical interest are portrayed graphically and discussed in a physical manner. It is observed that fluid’s velocity and temperature rises for radiation parameter but concentration of fluid drops down. Local motile density slightly enhances with Dissipation, Suction and Radiation factor while it drops down with Slip factor. When injection of fluid raised then skin friction coefficient, Nusselt number, Sherwood number and motile microorganism density also raised.
