摘要

研究了变流体性质(粘度和热导率)和磁偶极子对生物磁性麦克斯韦流体通过具有滑移速度和热生成/吸收的拉伸片的影响。采用相似变换技术得到自相似耦合非线性常微分方程。利用相似变量,利用MATLAB软件对具有边界条件的基本控制方程进行了变换和求解。通过图形分析和检验了不同相关参数如粘度、导热系数和铁磁参数对具有物理量的流动剖面的贡献。结果表明:随着铁磁参数、滑移参数、麦克斯韦参数的增大,速度减小,温度升高;为了保证模型的准确性,在一些极限情况下,将本文的数值结果与文献的数值和图形结果进行了比较,发现两者吻合得很好。达卡大学学报(自然科学版),69(2):109-115,2021 (7)

The Impact of Variable Fluid Properties on Biomagnetic Maxwell Fluids Past a Stretching Sheet with Slip Velocity and Heat Generation/Absorption
The impact of variable fluid properties (viscosity and thermal conductivity) and magnetic dipole on biomagnetic Maxwell fluid past a stretching sheet with slip velocity and heat generation/absorptionhave been studied. Similarity transformation technique is adopted to obtain the self-similar coupled nonlinear ordinary differential equations. Using similarity variable, the basic governing equations with boundary conditions are transformed and solved in bvp4c technique with MATLAB software. The contribution of different pertinent parameters such as viscosity, thermal conductivity and ferromagnetic parameter on the flow profiles with physical quantities are analyzed and examined through graphically. Results shown that with increasing ferromagnetic parameter, slip parameter, Maxwell parameter, velocity decreases but temperature increases. For accuracy of the proposed model to compare our numerical results in numerically and graphically with the previousliterature under some limiting cases and a good agreement is found. Dhaka Univ. J.
