摘要
现有分析的基本目的是仔细研究 Ellis 模型在磁场作用下的二维流动机制。此外,还讨论了热辐射、微生物生物对流和粘性耗散等参数对 Ellis 模型的热泳效应和布朗运动的影响。另一方面,对生物对流的特征进行了系统研究,以了解其在微生物开发采油、含气冲积盆地、生物微系统和石油建模中的广泛应用。在拉力作用下,粘弹性材料会根据粘弹性和弹性图解发生变化。在这里,我们认为这是由于主观旋转微生物悬浮液中的流体力学不均匀性和设计造成的。因此,本文对埃利斯流体的非稳态二维生物对流进行了理论和计算评估,该流体具有非线性辐射特征以及陀螺触觉微生物,阐明了这项工作的新颖性。本研究使用对流 B. Cs,通过使用一些合适的 B. Cs 和相似性条件将耦合 PDE 变为耦合 ODE。获得的 ODEs 采用 bvp4c 方案进行数值求解。在这里,我们详细研究了所有这些参数的物理效应,并用图形表示出来。我们发现,布朗运动和热泳参数值越高,温度越高,而普朗特数则下降。回转运动微生物导致佩克莱特数值升高时温度降低。
Thermo-physical properties of non-linear radiative flow of magnetized Ellis fluid comprising analysis of oxytactic microorganisms and nano-enhanced phase materials
The basic aim of existing analysis is to scrutinize the two-dimensional flow regime of Ellis model under the consideration of magnetic field. The effect of thermophoresis as well as Brownian motion for Ellis model with the impacts of parameters like thermal radiation, bioconvection of microorganisms and viscous dissipation are also deliberated. On the other hand, the features of bioconvection have been systematically examined for its extensive uses in microbial developed oil recovery, gas-bearing alluvial basin, bio-microsystems and oil modeling. Under the effects of tension force, viscoelastic materials change according to viscoelastic and elastic illustration. Here we considered it due to hydro-dynamics unevenness and designs within suspension of subjective spinning microbes. Therefore, this paper presents a theoretical and computational evaluation of the unsteady 2D Bioconvection flow of Ellis fluid, which has non-linear radiation features as well as gyro-tactic microorganisms, illuminating the novelty of the work. Here, convective B. Cs are used for the current study, coupled PDEs are changed into coupled ODEs by using some suitable B. Cs and similarity conditions. The acquired ODEs are numerically solved by using bvp4c scheme. Here Physical effects concerning all such parameters are studied in detail and represented graphically. We found that increasing behavior of temperature for higher value of Brownian movement and thermophoresis parameter whereas fall in Prandtl number. The gyrotactic microbes result in reduction for rising values of Peclet number.
