BACKGROUND
The purpose of this study is to investigate the electroosmotic flow of a hybrid nanofluid (Al2O3-Cu/Blood) with gyrotactic microorganisms through a bifurcated artery with mild stenosis in both parent and daughter arteries. The flow is subjected to a uniform magnetic field, viscous dissipation, and a heat source.
METHODS
The governing equations undergo the non-dimensional transformation and coordinate conversion to regularize irregular boundaries, then solve the resulting system using the Crank-Nicolson method.
RESULTS
In both sections of the bifurcated artery (parent and daughter artery), the wall shear stress (WSS) profile decreases with increasing stenotic depth. Nusselt profile increases with an increase in the heat source parameter.
CONCLUSIONS
The present endeavour can be beneficial for designing better biomedical devices and gaining insight into the hemodynamic flow for therapeutic applications in the biomedical sciences.
背景
本研究旨在探讨在母体和子体动脉均存在轻度狭窄的分叉动脉中，具有旋进微生物的混合纳米流体（Al2O3-Cu/血液）的电渗流。流动受到均匀磁场、粘性耗散和热源的影响。
方法
控制方程经过无量纲变换和坐标转换来正则化不规则边界，然后使用 Crank-Nicolson 方法求解得到的系统。
结果
在分叉动脉的两个部分（母体和子体动脉）中，壁面剪切应力（WSS）随狭窄深度的增加而减小。努塞尔特轮廓随热源参数的增加而增加。
结论
本研究有助于设计更好的生物医学设备，并深入了解生物医学科学中的治疗应用中的血液动力学流动。
